When I want a quicker cool-down period, I start the coach's engine and leave it running with the chassis A/C going full blast. This particular chassis has a very powerful A/C, so it cools down really quick in almost any temperature. However, I wonder how long should the engine (a small Mercedes-Benz diesel) be left idling without any negative consequences. Do you know? I've had it running in such occasions for up to 20 minutes or so, but I wonder if I should or not.

It would seem to be pretty easy to do as long as you have 50A service. Any time the temp is mid-90's or above it would be very welcome, as well as for quick cool-down when the coach is overheated. This would be a very welcome thing to have and something I will consider doing in the future.

That's exactly the kind of information I was looking for, thanks. Do you happen to recall what temp your rig was able to maintain at Gulf Shores? Were you able to keep it, say, 75 inside when the outside temps were 100+?
We stayed at Gulf Shores in our Intrigue (with two a/c's) a few years ago, miserably hot and humid, outside temps were well into the triple digits, but inside temps were around 90, at best. Not unbearable, but not too comfortable, either.

How about one of those roll around units that Home Depot sells for $300. Read about a guy in a 5er who needed extra cooling so he bought one of these. He liked it so well he used it all the time and used roof air for backup. You would have to make arrangements for the 3" exhaust tube (which also exhausts dondensate) but that would be a cheap solution if only needed occassionally. Below is the link and info.

I have 4 basement AC units. It is currently 99 degrees and the interior is 75 degrees (where I have my thermostats). The various units cycle off and on as needed. At this time, 2 of the 4 AC units are actually running so they are quite capable of dropping the temperature lower if desired. I have 50 amp service and a 12.5kw generator.
My AC's draw about 16 amps each so 32 amps per leg (64 amps total at 120 volts) when they are all on at the same time leaving me 18 amps per leg for other electrical usage.

We've been in Scottsdale, Az in September when it was well over 100 F in our 37'4" Allegro Bay and managed to stay comfortable. It has (2) 15,000 btu roof air-conditioners and I put out the awning on the driver's side of the coach, pull my day/night shades down to night, and insert one of these big insulated reflective form fitting sheets in the front windshield, then close the front crutain, and drop down the side window's and windshield sunshades. I beliebe it was 118 outside, but we were comfortable inside. Our daughter lives in Scottsdale and we come out here every year. I think a combination of (2) 15,000 btu units combined with a well insulated coach, a few window awnings, and a reflective/insulated front windshield insert, and you're in business! Oh, forget to mention, we have three Fantastic/Magic vents and I insert those insulated squares from CW in them. (2) 15,000 btu air units, good insulation, and shade from the awnings should work, even in August. Bagman.
