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..
