Westinghouse makes generators for every kind of RV, from a 33 lb unit for a camper van to a 12,000-watt tri fuel unit that can back up a whole house. The right one depends on three things: how many watts your RV pulls, whether you want to carry propane or gasoline, and how much weight you're willing to lift. This guide matches each Westinghouse model we carry to the RV it suits best.
Quick picks
| Your RV | Best pick | Why |
|---|---|---|
| Van or pop-up, no A/C | iGen1500c | 1,000 rated watts, 33 lb, as low as 52 dBA |
| Small trailer, light loads | iGen2550c or iGen2550DFc | 1,900 running watts with a TT-30R RV outlet |
| 30 amp trailer with one A/C | iGen4000DFc | 3,300 rated watts, TT-30R, remote start, gas or propane |
| 30 amp, more headroom | iGen5000c | 3,900 rated watts, TT-30R, up to 18 hours at 25% load |
| Budget, noise less important | WGen5300DFcv | 5,300 running watts, RV-ready and transfer-switch ready |
| Large rig, or RV plus home backup | iGen12000DFc | 12,000 peak watts, remote start, gas or propane |
Start with your air conditioner
For most RVers, the roof A/C decides the size. A typical 13,500 BTU rooftop unit runs on roughly 1,300–1,800 watts but needs a much bigger surge to start the compressor. Fridge, converter and lights add a few hundred watts more. That's why we point most 30 amp owners to the iGen4000 series (3,300 rated watts on gasoline). It starts and runs a single A/C with room to spare. The 2,550 and 2,800 models can run an A/C on some rigs, especially with a soft-start kit, but they leave little headroom.
Gas, dual fuel or tri fuel?
- Gas only (iGen1500c, iGen2550c, iGen4000c, iGen5000c, WGen5300sc): simplest, and full rated output.
- Dual fuel (models with "DF"): runs on gasoline or propane. Propane stores without going stale and can come from your RV's tank, but output drops about 10%. The iGen4000DFc, for example, makes 3,300 rated watts on gas and 2,970 on propane.
- Tri fuel (iGen12000TFc): adds natural gas. That matters only if you'll also hook it up at home.
Inverter (iGen) or open frame (WGen)?
For campgrounds, choose an iGen inverter model. They're far quieter (52 dBA on most iGen models), deliver clean power (3% THD or less) and sip fuel in economy mode. The open-frame WGen models give more watts per dollar and suit boondocking away from neighbors or doubling as home backup. See our inverter vs open-frame guide for more.
Safety features
Most Westinghouse generators we stock list a CO sensor, and most iGen models add automatic low-oil shutdown and overload protection. Check the product page for each model. All of them are for outdoor use only. Keep the generator well away from windows, doors and vents, including your RV's.
