Does anyone have electric dash AC?
It seems to me that there would be some merit in having an electric compressor for the dash AC. Mainly so that I could use it while stopped to supplement of even replace a roof unit. In my coach the...

Groover,
When you're doing your planning, most of the engine driven dash AC units I've worked on (cars mostly) have about 15,000 BTU of cooling capacity. So if you replace an engine drive AC with a 8,000 BTU unit, I think you'll be disappointed in the performance. In other words, make sure that your replacement unit has at least as much cooling capacity as the unit you're trying to replace. But I think, at best, that's ALL you'll be able to do, is to replace the cooling capacity of your engine driven unit. I think you'll STILL need your roof ACs to supplement in hot weather.
I don't know the size of your rig, but if you have a properly functioning dash AC and 2 properly functioning roof ACs, your rig should be able to be kept comfortable. If not, I think you have a thermal insulation problem OR your ACs aren't really operating up to specs.
I would put the money into a good cleaning and checkup on your existing ACs and run the dash & roof ACs as needed. $2700 buys a lot of gas/diesel. :)
Good Luck,
