A/C Cooling performance in a 34ft trlr.

[Mark Wiltrakis]

"One thing that few people seem to know is that you can actually collapse if you go from a very cold air conditioned room to a much higher temperature. In fact you place extreme stress on your heart if the temperature differential is more than 20 degrees."

I have to briefly (only VERY briefly) put on my cardiologist hat here for a reply: The problem with change of location into a very hot environment is peripheral vasodilataion (blood vessels in skin and elsewhere dilate, as they should, in response to hot temperatures). This lowers blood pressure, and "collapse" could follow. The heart is an innocent bystander and not the culprit, and not in particular danger.

I've followed this thread with personal interest. I used my A/C at the International rally in Salem with outside temp 103 two weeks ago. It was the first time I'd had the A/C turned on, and I had no idea what to expect. Here's my indoor/outdoor temp display. I'm very happy with my A/C!

My 94 34' would not keep the bedroom cool in the heat of the day. I put two new a/c units in the first replaced the one in the galley the other went in the fan opening in the rear bedroom. I also put in a dedicated circuit for the bedroom unit with a 20 amp circuit breaker. This unit plugs into the 20 amp circuit in the campground, along with the trailer using the 30 amp. This gives me the choice of using both or either of the units. With both units running it keeps the trailer cool in the hottest temps. I wired the units and put in the drain line, Camping world installed the a/cs.

IMHO, this is the best way to add a second A/C unit. It sure beats ripping apart a lot of the trailer to re-wire for 50 amp service, not to mantion the expense involved.
