Large camper with single AC

Actually kind of shocking they even produced a unit that big with 1 air con. Around 28-30ft, you are reaching the limit for a single unit.

I assume the rig is a 50 amp rig (just the current site is 30amp) and it's wired up for a second air/con. Bite the bullet and get the second unit. I'll bet you every time it gets up in the low to mid 80's, it will struggle to keep the inside cool with only 1 unit.

One temporary thing, you can try is if the aircon vents close off, shut down the bedroom and bathroom and close them off so all the cool air is going to the main living area during the day. Usually at night, you don't need as much cooling, so you can open them back up.

Hemling,

A couple of solutions from most expensive to cheapest

1. Add a double mini split Air Conditioner and replace the existing roof top unit.

2. Add a 2nd roof top unit and an autoformer, combined with a hybrid inverter/charger that does load support.

3. add a window or through the wall air conditioner to the rear wall. Autoformer for sure--but maybe not hybrid inverter/charger

4. add a stand alone A.C. unit, one with twin tubes.

Had I known then what I know now - lived in WI when we bought. Moved to Miami.

I have a 40' DP with two air conditioners - if I ever buy another one, it will have three air conditioners. I wouldn't own anything larger than my 26' TT with only one air conditioner.
