4000 Watt Generator

We have the 4000 in ours and does a good job with air or heat pump. We boondock or camp in forest and beach CG's with no power several times a year. Running the Gen in the morning on the heat pump and the coffee pot or the Micro. Two of the heavy use items at a time are fine adding the third is iffy. Same in the afternoon evening to charge batteries for the overnight heat/furnace if needed, watching TV and cooking dinner. If it really gets warm going down the road we use the GEN and AC to cool the coach on the last leg of the trip to have comfort after setup.

We use the Genny at rest stops to use the microwave for lunch and to run the roof air for a quick nap. We've used it when there are power failures at camp grounds... and at home. We moved out to the motorhome for two days during the last big power failure. The generator used less than a half a gallon of fuel per hour.

And yes, it ran the 15,000 BTU air conditioner fine.

It depends.
I can't imagine NEVER needing to run the A/C in an RV.
They can get REAL hot inside when sitting out in the sun.
I have a 28 foot C and find the 4K sufficient for A/C and microwave but that strains it a bit.
The front A/C is plenty for me when moving but I'm by myself.

I use my generator to run the AC frequently: when working on it - cleaning it or loading or stopped at a rest stop. and never have a problem cooling with it. I do not run it when driving as the dash is sufficient. However I never have anyone riding in the back section of the coach.

Many run the generator and house A/C while driving. It will not hurt anything.


In a C you can easily hang a curtain behind the cab to contain the cool air, and use the dash air only.
