We just purchased a 2011 Rockwood 8315BSS and we want to buy a generator for our trip out west. I can't seem to find anything about the size of the AC unit in the paperwork in the trailer .It's probably a 13,5000 BTU but wanted to make sure before getting the wrong size gen set. Was going to call FR with vin number but they don't seem to want phone calls as there is none listed on their sites. Also will this unit keep the trailer cool we will go through Texas, NM, and Arizona in middle of August....I've read through most of the post and what a wealth of information they certainly helped us with the final phase of buying the trailer and now getting it ready for the trip.

It isn't so much as just running the A/C as it is supplying the compressor motor startup SURGE current, especially for the subsequent restarts with head pressure.

Even non-inverter gensets that are always revved up to a fixed RPM often have problems with this. Since an inverter type genset may well be simply idling along when "hit" suddenly with a 3000-5000W A/C startup load they have even more problems.

Oftentimes the A/C motor's protective CB will cycle several times before head pressure declines enough to allow a restart.
