Alternative
Since I have no over-the-road Coach A/C unless I run the Gen & turn on the roof airs I've been thinking on how to supplement for the warm Arizona summer. Back in the day my company refurbished a number of corp jets. Typically the ole' bleed air system of cooling didn't work well on the ground or really below 12k feet. So I designed a 24v aux system for supplemental cooling. Their are such systems on the market for trucks, heavy equiptment, motorhomes and such. If your existing system is sound except the compressor etc. these could be incorprated into your system. The 24v option would use about 25 amp max under load which, should be doable with the batteries and alternators of the larger coaches. It could even be suplemented with some solar if you are somewhere the sun shines.. i have attached a jpg but there are many systems out there..

Aux Air System
Hi Tom,
This is the us link http://rencoolusa.com/dc-products/ i'm not sure what they cost... If I do it I'll just build one... not that difficult... My holdback is my alt size it's pretty wimpy... Could run on hyd but more issues and trouble.. Heading up the Mt in the am.. wish me luck.. on the down hill side.. I'll be in behind the slowest truck! In loading up found I need more room.. the little lady has filled it up for a two day trip..
Regards,
Jimmy

Hello Forrest,
By any chance do you still have your old AC units and any parts available for sale? I need the board for the twin compressor. RVAC 305-2547 rev a. I know it is a long shot, as your post is 4-10-2010. How are the roof ACs working out? My coach is 96 #410.
Thanks.
Nando

I still have my basement airs. I was able to find the newer type board and thermostats.
But mine is the older Dometic single compressor, a '93.

I have a friend who has a 1985 Prevost (nice wood interior just like new), he has an OTR A/c, and his coach is a wide body coach, but from inside just like 96" coaches! That OTR's AC is taking too much from the walls!! making the coach narrow in width from inside, when I measure it from wall to wall from inside, its 7.5" smaller than my coach (Newell 1988)!! This is too much!
