Battery
I own a 1981 Coleman Sequoia, which has a roof mounted A/C unit. Is there a way to run the trailer and A/C off of a battery? I saw it done on a larger trailer.

Trailer itself yes, A/C not really. 12v fan might help but really if you need A/C 24/7 I recommend you find a camp with electric power.

12v will run lights, water pump(if equipped), fridge on propane (if needed), furnace blower etc. If you will be camping off-grid you will probably want 2+ batteries, relamp to LED lights and maybe add some solar (100+ watts?). If you want to run/charge small 120v items you will need a 100 to 300 watt inverter that draws power from the battery.

That would be one HUGE generator.
3000 WATT maybe ?? :B
lol, um, ya, watts! But heck, a 3000 amp generator would also run the op's A/C, lights and several neighbors RV's as well!- No. You need 120 volts to run your AC unit

3000 WATT maybe ?? :B- NO! A typical A/C unit draws at least 15amps at 110VAC, 1650 watts. A high end single car battery can supply 80amps at 12VDC or 960 watts for about 1 hour. Battery would be dead in well under an hour. Now add in the loss of energy going thru a 12vdc to 110vac inverter and its even less.
What you need is a 3000amp generator such as a Honda or Yamaha. Then you could easily run your trailers lights and A/C for hours. - With enough batteries and a way to charge them, yes, theoretically. Not for you however.
- What you saw, batteries running an A/C, you wouldn't have seen for very long or a TT battery bank of a size to be completely crazy. Running the trailer, sure.
- There is no PRACTICAL way to do that on a small trailer.
But some "geniuses" here will certainly try to tell you otherwise.
The amount of battery power required is just too much.
A much more practical solution is a portable generator with enough capacity to supply your maximum requirements.
