do floor model/stand alone a/c's help if you only have 1 roof 13K unit?
Just asking.
You can buy a 'portable air conditioner' that has TWO air ducts, and it will bring in outside air, dump all the room heat into that air, and blow out really hot air through the other tube. It will effectively cool the RV and would be a good fix get you thought a miserable situation, but they will cost around $750.
Chances are that most local hardware stores will stock a single tube portable A/C. It takes inside air, heats it and dumps the heat into that 200 CFM air stream, and sends that air outside. Problem being that 200 CFM of humid and dusty air will infiltrate back in, warming the RV all the time, and you will not really ever get it cool.
Home Depot sells portable A/C units. You can sort 'single pipe' and 'Double pipe' - but most of what they stock in the local stores are single pipe, that cost around $100 less to buy them.
I would be looking for a cooler motel room, or going back home if it was 90F and I could not sleep!
