Yup, forgot to convert 120 volts to 12 volts - I’ll just suck it up and run the generator

Depends. If there's no one in the rear area and the temps are staying comfortable then we don't. I leave the middle door closed and only run the front zone when we travel though.

Our class A has an auxiliary heater that is a huge heater coil in the bedroom area with a fan. When we travelled in the spring overnight we ended up learning what that switch does. Kept the coach warm without running the generator.

After traveling for 15 years with a TT in the summer and getting to a destination having the trailer interior at 90+ degrees and taking a couple hours to cool everything down, I’ll gladly run the generator to keep it comfortable for when we get to our destination! Well worth the extra $10 dollars or so a day it costs to run it.

Currently in eastern US where we haven't boondocked much. Ran the AC last week and put the thermostat down to 67 to run a couple of our ACs to exercise the generator. Did it again 1.5 months ago. I emagine we'll run them during the hot days when travelling this summer.

The below list explains when/how we have used the dash ac, coach ac, generator in our mh's.


1. When initially leaving, outside air temps determine if the dash air is turned on.
2. If needed, "always" set dash ac on Maxcool and fan speed of low, med or high.
3. Additionally, most mh's will usually have (2) fans above the windshield which usually are intended for defrosting if needed but we've found these help circulate the ac air when turned on low or med. High seemed to be a little to noisy.
4. When/if outside start going upwards,(90+) we will then turn on the generator and the front roof air to start assisting the dash air. The roof air stat is set to 70 degrees and the fan speed to manual high. Compressor will kick on/off as needed while the fan continually circulates the air throughout the coach. Whe will also use the described fan speed method for the roof air(s) when we are stationary at a park and the outside air is in the 90s. They are made to run; use them.
5. We have occasionally had to turn on a second roof air when traveling if the outside air continue rising upward. Nothing like arriving at your destination in a pre-cooled coach.
6. Fuel usage for us has been usually in the 1/2-3/4 gal range per hour with diesel generators.
7. Our yrly hr usage will regularly be 250-300hrs.

Just like with our 33' toy hauler TT, we run our rooftop AC via Onan genny to keep rig cool while traversing down the road, nothing like arriving to your destination with a pre-cooled rig. In our class A as weather conditions dictate we certainly run our AC units via genny without ever considering costs compared to comfort, if you are not bedding down in a tent or truck bed you are glamping.

Pretty simple really, just do what works for you. Forget fretting about putting hours on your genny, Onans simply love to run and often times issues begin with their stagnation from lack of use. As for fuel costs, I pay more for a cup of coffee than having onboard Onan power our entire rig for a few hours, why have all the amenities an RV provides if you can't use them whenever and wherever.
