Overview
Tired of planning trips around a hookup? The maker says the 2027 OPUS OP15 Bunk Model and OP13 support up to a week off-grid. OPUS Camper detailed the updates in a release RVBusiness published on October 30, 2026. Specifically, the company says they target power, storage, and connectivity, the areas owners and dealers requested most. Below, we check the week-long claim against the maker’s own numbers.
Both models now carry 800 W of rooftop solar and a 600 Ah lithium battery. In addition, the release lists a Victron inverter/charger and a factory-installed exterior Starlink port. The maker’s model pages also list an automatic lifting roof, an ensuite, and 63 gallons of fresh water. Overall, these are hard-sided campers with a push-button lifting roof, not tent trailers. For a closer look at the build, see what makes a trailer truly off-road.
The maker’s site also lists $68,400 for the OP13 and $73,400 for the OP15, plus title and tax. The pages carry no model-year label, so confirm 2027 pricing with a dealer. RVBusiness carried the release.
Both models carry two kitchens, covered below, and a sink and stove work best on level ground. The Camco FasTen interlocking blocks build up under a wheel, and the Camco wedge leveler adds up to 3.25 inches of lift.

What Changed on the 2027 OPUS OP15 and OP13
The release describes a completely overhauled electrical system on both models. It also lists a Victron MPPT solar charge controller and a 3000 W Victron inverter/charger. The model pages list a smaller 2000 W unit, so confirm which ships. Meanwhile, a Victron BMV-712 Smart battery monitor replaces the original unit. Together, the parts form what OPUS calls an app-connected power platform.
The release covers cooking and storage too. For 2027, both models feature dual kitchens. Each has an interior kitchen, including a sink and a two-burner stove. Outside, a slide-out kitchen adds a sink and four-burner cooktop. Also, the exterior pantry gains lighting, and a large front storage box holds jerry cans, propane cylinders and general gear. Inside, the OP15 adds wall cupboards in the bed section. The OPUS OP13, in contrast, adds bed-section cubbyholes and a wall cupboard. It also gains a front tire carrier, a rear rack holder, and an exterior MOLLE panel.
On connectivity, the release says each model includes a factory-installed exterior port for Starlink, so you mount and cable the antenna directly. The maker’s model pages do not list the port, so confirm it with a dealer. I have used Starlink for the better part of five years, so a factory mount is an especially welcome detail. Our Starlink Mini camping setup guide covers the basics, such as power and mounting.
How Far 800 W and 600 Ah Go Off-Grid
Next, check the week-long claim. OPUS lists 4 to 7 days off-grid for the OP13. The OP15 page says the pairing keeps a family out for most of a week. However, the maker adds one caveat. Real range depends on the weather, the heat, and how hard you run the refrigerator and air conditioning.
Here is the arithmetic, which is mine and not the maker’s. First, at a nominal 12 volts, 600 Ah stores about 7,200 watt-hours. Meanwhile, 800 W of panels with five full-sun hours tops out near 4,000 watt-hours a day before losses. Therefore, a full-sun day returns at most a little over half the stored energy, and cloudy days return less. In short, the sun decides where you land in the maker’s 4 to 7 day range.
Charging from the tow vehicle also fills gaps when the sun fades. The OP13 page lists optional DC-DC charging. Our DC to DC charger wiring guide explains why lithium banks need this hardware.
OPUS OP15 vs. OP13
Since both models share the same power system, the choice comes down to size. The OP15 sleeps four, with an RV king bed and twin bunks. However, the OPUS OP13 sleeps two on an RV king bed. It is also shorter and lighter, at 21 feet and 4,927 lb dry. In contrast, the OP15 measures 23 feet and 5,430 lb dry. Both list a 6,600 lb GVWR and 7 feet 11 inches of travel height with the roof down. The OP15 also costs $5,000 more, at $73,400 against $68,400.
Tongue weight is 445 lb on the OP13 and 483 lb on the OP15. For towing, the maker points to a half-ton pickup or full-size SUV. Look for a 7,000 lb rating or more on the OP13. The OP15 needs 7,500 lb or more. In addition, a 2019 forum post on the launch OP15 says it exceeds a Wrangler Unlimited’s tow rating. If you tow with a midsize truck, check your rating first. Our look at towing a heavy off-road camper shows how those numbers play out.
Before your first trip, weigh the tongue instead of trusting the brochure. The Sherline LM 1000 reads up to 1,000 lb, well above the 445 lb and 483 lb listed tongue weights. On the road, the TST 507 kit with four cap sensors tracks tire pressure on a trailer, so match the sensor count to your tires.

What This Means for You
The release tells you what changed. These three checks tell you what to do about it.
First, confirm the inverter size. The release lists a 3000 W Victron inverter/charger. However, the maker’s OP13 and OP15 pages list a 2000 W Victron inverter. Ask your dealer which unit ships on a 2027 build before you sign.
Next, match the camper to your truck. Tongue weight counts against your truck’s payload, so a half-ton pickup is the starting point on both models. The OP15 leaves 1,170 lb of cargo capacity under its 6,600 lb GVWR. By comparison, the OP13 leaves 1,673 lb. Loaded to 6,600 lb, the OP13 leaves 400 lb of margin on a 7,000 lb minimum rating. The OP15 leaves 900 lb on its 7,500 lb minimum.
Finally, weigh the owner record. We read through owner forums, and evidence on the previous models is thin. Forum posters like the hard-sided family layout. Some, however, worry about build quality. Those are forum comments, not test results.
Final Thoughts
If hookups shape your trip plans, the 2027 OPUS OP15 and OP13 deserve a dealer visit. The solar, lithium bank, dual kitchens and factory Starlink mount all point toward longer, easier camps. For families, the OP15 layout is especially appealing, since it adds bunks.
I have not towed or tested either camper, so this is not a review. My read rests on the maker’s numbers and the owner record. Treat the week off-grid as the maker’s goal, since weather decides the real number. First, settle the inverter size, the tow rating and the price. Then weigh the 2027 OPUS Camper models against a lighter trailer, such as the 2027 nuCamp TAG XL Lite, or a rooftop tent. A quiet week at camp is worth the homework.
