Overview: Which Truck Cap Types Fit Your Rig
Truck cap types fall into three groups: stainless steel flat-pack caps, fiberglass shells, and soft retractable toppers. Steel suits a high tent roof rating and big side doors. Fiberglass gives you a lockable, paint-matched cap at a lower hard-shell price. A fabric topper gives you the lowest cost and an open bed on demand. This guide compares all three using maker specs checked on November 1, 2026, plus what owners report after years of use.
Before the comparison, a quick note on names. Truck cap, topper, camper shell, and canopy all describe a cover for the pickup bed, and LEER calls the terms interchangeable in everyday use. So this guide says cap for hard shells and topper for soft ones.
Pop-up campers such as the AT Overland models sit outside these three groups, and aluminum caps get a short section below. A tonneau cover is a different product. Softopper’s buyer guide says it lies flat across the bed rails and limits load height, while a topper gives standing cargo height.
Truck Cap Types at a Glance
The table below sets the three groups side by side. Weights and prices come from the sources named in each section, and roof ratings are the published figures.
| Key Fact | Stainless Flat-Pack | Fiberglass Shell | Soft Topper |
|---|---|---|---|
| Example | RSI SmartCap EVO | LEER, ARE, SnugTop | Softopper |
| Weight | Close to 200 lb (EVO Sport) | 150 to 250 lb | 18 to 48 lb |
| Price | $3,695 to $4,995 by truck | $2,200 to $4,500 or more | About $1,000 to $1,300 |
| Roof rating | 330 lb moving, 770 lb parked | Standard LEER: 220 lb moving, 1,000 lb parked | Use a bed rack for tents |
| Security | Keyed locks | Locking | No lock |
| Removal | Likely three or four people (maker lists 15 minutes) | Two people or a hoist | One person, minutes |
Prices vary by truck, so treat each range as a starting point. Fit is vehicle-specific. Softopper says a topper must match your make, model, year, and bed length, so confirm a short or long bed before you compare prices.
Whatever cap you pick, you still sleep on the bed floor. Because a foam pad, a rechargeable lantern, and a battery fan fit under any cap, they outlast a cap swap.

Stainless Steel Flat-Pack Caps: Strong Roof, Big Doors, High Price
The RSI SmartCap EVO is the best-known stainless steel truck cap. According to an OutdoorX4 field review, it ships as five stainless steel panels you or a dealer assemble. The reviewer built his Sport model in about two hours with three people. He also notes mounting or removing it will likely take three or four people, and the cap weighs close to 200 lb.
Notably, the roof numbers favor a heavy tent build. SmartCap rates the EVO roof at 330 lb while you drive and 770 lb when you park. Its side openings run about 17% taller than most fiberglass caps, according to the maker, and the EVO Sport page lists a three-year warranty.
Expect to pay for the strength. The same page also lists truck-specific prices from $3,695 to $4,995. A cheaper flat-pack option exists, though it uses aluminum instead of stainless. Our OPENROAD flat-pack truck cap review covers a 112 lb cap at $2,899.99 for the Colorado, against about $4,395 for the SmartCap EVO Adventure (EVOa) on the same truck. OPENROAD supplied the cap.
Steel Cap Owners Love the Doors and Report Leaks
Owners on Tacoma, F-150, and Colorado forums praise three things: the looks, the gullwing doors, and a rigid build with no flex. I think gullwing doors are the best reason to buy a stainless steel truck cap, since you reach gear from beside the truck.
Complaints follow a pattern, however. Water leaks at seams and sliding windows top the list, including on some professional installs. Next come stiff latches, and some owners say quality control and support do not match a price of $4,000 to $5,000. Still, several other owners report no problems after sealing the bed, so read threads for your own truck.
Fiberglass Shell Caps: Paint-Matched, Locking, and Easier on the Budget
Fiberglass is the classic pickup cap. LEER, ARE, and SnugTop mold the shell to the truck. LEER lists cab-high caps, mid-rise caps standing above the cab roof, and taller profiles, with paint-matched finishes. Pricing follows the options. LEER’s 2026 cost guide estimates $2,200 to $4,500 or more for a fiberglass truck cap and $3,000 to $5,500 or more for a premium color-matched one.
Weight is the trade-off. Softopper’s buyer guide puts hard fiberglass caps at 150 to 250 lb or more, and owners report the same range. Therefore, plan on a two-person lift or a garage hoist whenever you remove the cap.
Cap Height and Roof Rating Decide the Camping Fit
Owners who sleep in the bed mostly prefer a mid-rise cap over a cab-high one. They also advise checking garage clearance before you order. Roof ratings, however, need more care. Our rooftop tent on a truck cap comparison lists a standard LEER fiberglass cap at 220 lb moving and 1,000 lb parked. Owners quote anything from 150 lb to 500 lb for other models, so get the rating for your exact cap in writing.
Fiberglass Quality Varies by Brand
Opinions differ by brand. ARE draws the most complaints about window leaks and fit, although some ARE owners are happy. LEER and SnugTop owners praise dry, lockable storage and report hard off-road miles without cracks, including on caps built for commercial work. Compare the exact model, not only the material.
Where Aluminum Caps Fit
Aluminum is the other hard-shell choice. LEER’s cost guide lists basic aluminum caps at $1,200 to $2,200 and premium commercial ones at $2,000 to $4,000 or more. These suit work setups with shelving, ladder racks, and side-access compartments. LEER’s fiberglass-versus-aluminum guide says weight depends on the exact model, so compare specs before assuming aluminum is lighter.
Soft Retractable Toppers: Lowest Price, Lightest Weight, No Lock
This type wraps vinyl or twill fabric around an anodized aluminum frame. Softopper’s buyer guide lists weights of 18 to 48 lb, no-drill C-clamp installs in about an hour, and prices of about $1,000 to $1,300. The top folds toward the cab, so you get a full open bed in seconds.
Owners back the low cost. One owner paid about $950 new in 2024, and used units sell for $250 to $350. In a long-running Tacoma World thread, one owner reports removal in under 10 minutes. The speed is, in my view, the best reason to buy one.
Soft Toppers Trade Away Security and Age Faster
Fabric offers no lock. Softopper’s own guide says a fabric top will never match a locking fiberglass cap for theft deterrence. It also warns seams sometimes leak in hard rain, so seam sealer is available. Long-term owners report fabric shrink and cracked plastic clips after four to seven years. One owner also replaced the rear window about every four years.
For tent loads, mount a bed rack instead. Softopper sells racks built to attach to the factory bed rails and work with the top closed, in Safari mode, or retracted. As a result, the rack carries the tent weight and the fabric does not.
Weight, Payload, and Roof Load Across Truck Cap Types
Every cap uses part of your payload. Payload equals GVWR minus curb weight, and our payload capacity and GVWR guide suggests keeping loads at or below about 80 percent of rated payload off-road. Typical midsize trucks have a rated payload of 1,100 to 1,700 lb. The cap, passengers, and gear all count against it.
Add up your load before you order. For example, our Tacoma versus Tundra build math assumes a conservative 300 lb steel shell, 200 lb for a tent and rack, 150 lb for drawers and a fridge, and 250 lb of water. It then adds two adults and a dog. As a result, many built Tacomas end up with under 900 lb of usable margin.
Heavy caps also load the rear axle, so weigh the cap you want against your payload before you order.
Roof ratings come as two numbers. The moving rating applies while you drive, and the parked rating applies at camp. Typical rooftop tents weigh 100 to 200 lb empty, and some hardshells run closer to 250 lb. So a 220 lb moving rating leaves little room for crossbars or a second load.
Security, Weather, and Dust Across Truck Cap Types
Hard caps of both materials lock, so they suit tools and camera gear. Fabric tops hide cargo but offer no lock. Steel owners add one caution: several report stiff keyed latches and doubt the locks resist a determined thief.
Dust and water reach the bed under every cap. As our truck bed seal guide explains, truck boxes are not leak proof. Sealing runs from $25 for a tailgate kit to about $100 for a full job. In addition, SmartCap fits a filtered positive-pressure vent to every SmartCap, which helps keep road dust out.
Install quality matters as much as the cap itself. Owners report leaks from wrong torque and popped gaskets on professional installs. Follow the maker’s torque spec, then seal the bed before you load it.
Three simple items close most gaps: a tailgate seal, a cap rail seal, and butyl tape. Because each is a universal strip or roll, you cut it to fit your own bed.

How to Pick Among Truck Cap Types
Start with how you use the truck, then match the cap to the job.
If You Carry a Rooftop Tent
Choose stainless steel, or a fiberglass shell with a written roof rating for your tent. Get the moving and parked ratings for your exact model in writing, and run the payload math first. A fabric topper holds a tent only through a bed rack.
If You Want Lockable Storage for Daily Driving
Fiberglass fits best here. The paint-matched finish blends into the truck, and it costs less than stainless. Pick a mid-rise height if you plan to sleep in the bed.
If You Haul Tall Loads Between Trips
A soft topper leaves the bed open when you need it. In return, you give up security and some service life for a lower price and fast removal.
Owners repeat four regrets, and each has a fix. Wrong height: choose mid-rise if you sleep in the bed, and measure garage clearance first. Assumed tent rating: get the moving and parked numbers for your exact cap in writing. No removal plan: steel needs three or four people, fiberglass needs two or a hoist, and a topper needs one. Expecting security from fabric: a topper has no lock, so keep valuables out of the bed or choose a hard cap.
Final Thoughts
Picking among truck cap types depends on which tradeoff you accept. If you want a tent on the roof and wide-opening doors, stainless steel earns its price, though you should budget for sealing and a careful install.
For a lockable, good-looking cap at lower cost, fiberglass is the balanced choice. Check the brand and the roof rating, because owners report real differences between models.
If you haul as often as you camp, a fabric topper is the budget answer. It will not stop a determined thief, and the fabric ages after several years, although few options keep the bed this flexible.
If you carry a rooftop tent, my pick is stainless steel, because it publishes a 770 lb parked rating. A fiberglass shell works too once the maker confirms a tent-rated roof in writing. For everyone else, start with fiberglass in a mid-rise height, and weigh your payload before you order.
FAQ
What are the main truck cap types?
The main truck cap types are stainless steel flat-pack caps, fiberglass shells, and soft retractable toppers. Aluminum caps also exist, and the OPENROAD flat-pack aluminum cap in our review weighs 112 lb. Pop-up campers, such as the AT Overland models, sit outside these three groups and get their own coverage on this site.
How much do truck cap types cost?
Softopper lists soft toppers at about $1,000 to $1,300. LEER, in contrast, estimates $2,200 to $4,500 or more for fiberglass. SmartCap lists its EVO Sport from $3,695 to $4,995, depending on the truck.
Will a fiberglass truck cap hold a rooftop tent?
It depends on the model. A standard LEER fiberglass cap lists 220 lb moving and 1,000 lb parked on our rooftop tent page, but owners quote ratings from 150 lb to 500 lb. Get your cap’s rating in writing before you mount a tent.
Is a soft topper waterproof?
Softopper calls its top weather-resistant, not waterproof as a system, because seams sometimes leak in hard rain. Long-term owners report a drier bed once they seal the seams.
How long does a soft topper last?
Owners report fabric shrink and cracked plastic clips after four to seven years, and one owner replaced the rear window about every four years.
