Off-grid RV capability starts with the power system
An off-grid RV is only as capable as its weakest system. Plenty of trailers wear the label because they have a solar panel on the roof, then send you hunting for a hookup after two nights. Real off-grid capability comes from energy, water, and climate systems sized for a week, engineered to work together.
That is the standard the Evotrex-PG5 was built to. It supports 7+ days off-grid with daily HVAC and appliance use, and this page breaks down the systems that make that possible.
An energy system built for weeks, sized in kWh
Most trailers marketed as off-grid capable carry a 200 W solar panel and a 1.2 kWh lithium battery. That runs lights and phone chargers. It does not run air conditioning, an induction cooktop, and a full-size refrigerator.
The PG5 takes a different approach. A massive LFP battery pack, 1.5 kW of integrated rooftop solar, and a quiet automotive-grade gasoline generator run as one smart integrated system that delivers 270+ kWh of usable energy per cycle. The generator is powered by gasoline, widely available anywhere. A full 20 gal tank delivers up to 225 kWh, about 11.25 kWh per gallon, which is up to 50% more usable energy per gallon than typical RV generators. Energy is stored in the battery, so you get quiet power on demand without the generator running at the same time.
Climate control with no propane to manage
Heat and cooling are what actually drain an off-grid RV. The PG5 runs a 17,000 BTU electric HVAC system with no propane furnace, no regulator issues, and no second fuel to track. In cold weather, residual heat from the generator is repurposed to warm the cabin efficiently, and tank heater pads keep the water system operational in cold temperatures.
The battery itself is rated from -22°F to 140°F, with ultra-safe LFP chemistry engineered to the standards used in the electric vehicle industry. The climate system works in the same places the battery does, which is to say almost anywhere.
Water and appliances that hold out as long as the power does
An off-grid recreational vehicle needs more than electrons. The PG5 carries 60 gal of fresh water, enough for extended trips without rationing, plus 30 gal grey and 30 gal black tanks. A tankless instant water heater delivers hot showers on demand in the full dry bath.
The all-electric kitchen runs a two-burner induction cooktop, a 3-in-1 convection microwave oven and air fryer, and a 10 cu. ft full-size refrigerator. Because the whole system can output up to 12 kW, you can use the entire kitchen at once.
A chassis that reaches the sites worth staying at
Off-grid capability also means getting there. The PG5 rides on a high-strength automotive-grade steel chassis with a dual-axle configuration, air suspension, and 33" all-terrain tires. It is engineered to access off-grid, primitive, and dispersed campsites with confidence, and adjustable air suspension lets you raise the trailer for extra ground clearance on rough approaches.
TowSync™ adaptive tow assist continuously adapts to road conditions and syncs with your tow vehicle, and it is designed for electric, gas, and diesel trucks alike.

Frequently asked questions
How long can an off-grid RV stay out without hookups?
It depends on the energy and water systems. The PG5 supports 7+ days off-grid with daily HVAC and appliance use, drawing on 270+ kWh of usable energy per cycle and 60 gal of fresh water.
Is the PG5 an off-grid motorhome?
No. Motorhomes are self-propelled vehicles you drive. The PG5 is a towed travel trailer, which keeps the living systems and the drivetrain separate and lets you leave camp set up while you explore in your truck.
How does an off-grid RV recharge its battery?
The PG5 recharges through 1.5 kW of rooftop solar, its onboard gasoline generator, regenerative braking while towing, and a NACS connection when you do have access to power. The system manages charging automatically.
Does the generator run all the time off-grid?
No. The energy it produces is stored in the 43 kWh LFP battery, so the trailer runs quietly on stored power and the generator engages automatically when the battery is low.
When the systems are sized for the trip, off-grid stops being a compromise and starts being the point. Preorder the Evotrex-PG5. From $119,990.
