Overview
Tune Outdoor now offers its M1 and M1L pop-up truck campers for the Ineos Grenadier. The company also launched eight retrofit accessories, from roof racks to a Starlink Mini mount. Truck Camper Magazine published both announcements on November 13, 2026, in an interview with Tune’s Head of Marketing, Rose Bythrow. We have not tested any of this gear, so the product claims below come from Tune and its store.
Tune thinks its M1 might be the first full pop-up topper built for the Grenadier. For the basics of the camper, read our Tune M1 truck camper review first.
How Tune Outdoor Fit the Grenadier
Tune completed its first M1 installation on a Grenadier. The owner added a lift, and the Grenadier was already tall. As a result, Tune’s installers needed a stepladder to reach the camper, and Tune calls it the tallest camper installation it has done to date.
The bed rails have a wavy profile, so Tune had to drop the mounting layout it uses on a standard pickup. Instead, Tune engineer Evan Costello flew to Utah to measure the owner’s truck and take photos. He then designed custom bed rail caps to match the rail shape. Bythrow says the finished interior feels comparable to Tune’s Jeep Gladiator setup, which is Tune’s own description.
Tune’s build gallery photos show a Quartermaster, Ineos’s pickup version of the Grenadier. The interview never names the model, so ask Tune to confirm fitment on your exact truck before you order.
Tune will add the Grenadier to its online configurator soon. It gave no date and no Grenadier price in the interview, so ask Tune directly about timing and cost.
One of the eight new accessories is a pair of T-track mounts for MAXTRAX MKII recovery boards, covered below. The mounts do not include the boards, so you buy those separately. This pair is the MKII set the mounts are built for.
MAXTRAX MKII Vehicle Recovery Board (Gunmetal Grey)
The MKII is the board set Tune's new T-track mounts are made to carry.
- Sold as a pair of boards
- Built for recovery from sand, snow and mud
- Matches the MKII set Tune's mounts hold
- High cost for two boards
- Boards and Tune's mounts are separate purchases
What the Eight New Tune Outdoor Accessories Cost
Tune says all eight accessories fit existing M1 and M1L campers, and Tune offers to ship the upgrades to your door. Only the camper jacks differ, because they use model-specific mounts. The prices below come from Tune’s store on November 13, 2026, and some are starting prices. According to the store, jack shipping is costly, and pickup at Tune’s Denver headquarters is free.
| Accessory | What It Does | Tune Price |
|---|---|---|
| Camper jack system | Four jacks with removable mounts; separate M1 and M1L versions | $1,450 |
| Roof racks | Four brackets on the upper T-track; 220-pound capacity | $650 |
| MAXTRAX MKII T-track mounts | Two mounts; boards and mounting pins not included | $150 |
| Starlink Mini mount | Slim bracket on the interior upper T-track | $75 |
| Rear door bug screen | Magnetic closure; Tune says it fits more than 70 truck and camper combinations | $250 |
| Anti-condensation mat | Adds airflow and cushioning under the mattress | $150 |
| Awning door with slider vent window | Screened sliding window; made to order, 6 to 8 weeks per the store | From $700 |
| Grab bar | Entry handle; Tune recommends mounting it above the rear door | $100 |
| One of each, at starting prices | All eight accessories | $3,525 |
Starlink Mini Mount
I have used Starlink for about five years, first on the larger dishes and now on the Mini. At camp it lets me run my businesses, so I stay out longer instead of driving back toward cell coverage. I have not tested Tune’s mount. If I owned an M1, though, a $75 bracket for a dish inside the camper is the accessory I would order first.
Tune says it tested the Mini through its regular FRP and Sunblocker FRP roofs before it designed the mount. Also, one customer ran a Mini through a Sunblocker roof for six months without issues. Tune gave no speed or signal-loss figures. You still drill two holes in the dish’s existing mount to bolt it to Tune’s bracket. Our look at why the Starlink Mini now pays for itself shows the cost case.
Comfort and Recovery Accessories
The bug screen has magnetic closures and bottom weights, and Tune says it closes behind you as you walk through. On Tune’s site, the Find Your Bug Screen tool picks your size from your truck make and model. Tune added the anti-condensation mat after customers in the Pacific Northwest and Florida reported moisture. For DIY installs, Bythrow fitted the MAXTRAX side mounts herself in about 15 minutes, and Tune estimates 15 minutes to swap an awning door.
Tune Outdoor Roof Racks and Jacks
Once the mounting plates are on the camper’s T-track, the QuickConnect jacks need no tools. First, you line up the slots with the studs on the plate. Next, you push the mount flush, lift it into place, and tighten a thumb screw by hand. Tune says most customers who buy jacks plan to store the camper in a garage, while many owners leave it on the truck full-time.
The roof racks accept common bar-clamp accessories, including most cargo boxes and ski racks, according to Tune. Four brackets attach to the upper T-track with hammer nuts. You need T30 and T40 Torx drivers, a tape measure and a torque wrench. The racks weigh 16 to 20 pounds depending on truck size, and Tune tested them on show vehicles for almost six months. Tune recommends unloading gear while the roof is down. To raise the roof with gear on the racks, Tune offers replacement struts rated up to 80 pounds.
Tune says the rack T-track also takes gear anchors and ratchet straps. Whatever you strap on, stay under the racks’ 220-pound rating. This AUGO four-pack of 15-foot ratchet straps lists a 733-pound working load, so the straps are not the limit.
AUGO Ratchet Straps Heavy Duty 4 Pack -15 FT - 2200 LB Break Strength – Ratchet Tie Down Straps with Safety Lock S Hooks - Cargo Straps for Moving, Appliances, Motorcycle – Soft Loop Tie Down Straps
A four-pack of 1 inch by 15 foot ratchet straps for tying down gear on roof racks.
- Four straps in one pack
- 15-foot length for bulky gear
- Safety lock S hooks and soft loops
- Easy to overtighten on a light load
- Working load limit is higher than the racks allow
Tune M1 vs. M1L
The Grenadier fitment covers both campers, so you choose between them. Tune lists the M1 at 400 pounds and 6’4″ of headspace, with weight and dimensions based on a 5-foot Tacoma camper. Interiors start at 269 cubic feet on midsize trucks and 323 cubic feet on full-size trucks. Tune has not said which range the Grenadier falls in.
| Specification | Tune M1 | Tune M1L |
|---|---|---|
| Base price | From $12,999 | From $8,999 |
| Width | 72 inches | 60 inches |
| Sleeping layout | East to west queen | North to south |
Because the M1L is slimmer, Tune built wider jack brackets for this model. The M1 offers more interior room. For a lower price and a narrower build, look at the M1L instead.
What This Means for You
If you own or plan to buy a Grenadier, note one fact first: Tune has shown a single finished install and gave no Grenadier price in the interview. Email Tune your truck model and bed type, and ask for a written quote naming the bed rail caps, the lead time, and your install date. Tune installs at its Denver headquarters or through a dealer. A $500 deposit comes first, then at least 50 percent to start production. Also check your garage and trail clearances, because a lifted Grenadier with a topper is the tallest build Tune has installed.
Next, weigh the whole setup. The M1 starts at 400 pounds, the racks add up to 20 pounds, and Tune rates them for up to 220 pounds of gear. Together, those come to about 640 pounds before bedding, a Starlink Mini and people. Tune gave no Grenadier payload figure, so check the sticker on your door jamb. Our payload problem guide shows how to add it up.
If you already own an M1 or M1L, you get low-cost upgrades with no new camper. At starting prices, a base M1 at $12,999 plus all eight accessories totals $16,524. Skip the jacks if your camper stays on the truck, and the other seven add $2,075. Buy the MAXTRAX mounts only if you carry boards.
Final Thoughts
Tune Outdoor now offers Grenadier owners a full pop-up camper, and Tune says it might be the first. However, the proof so far is one install and one set of photos. I would wait for the configurator and a written quote before I paid a deposit. Current owners have the easier choice, because the $75 Starlink mount and the $100 grab bar cost little and fit every M1 and M1L.
