true about the GM A-6, when i put my system in i used a sanyo compresser, they are smooth and very quiet. http://users.myexcel.com/roncarter/splitSystem/ go to this website to veiw what i did on my 06, it works great, one compresser, 2 evaporators and a single space saving condenser. we never run the roof airs on the road, no need. i have a eveporator in the front and one in the seat of the dinette. Best single thing i ever did to this bus.

Thanks for posting. That was the one I was referring to.

Nice set up Tekebird. I just hope TWO compressors off the front of the engine won't be too much power for that camshaft (I'm sure you'll find out one way or another). The A6 compressor (6 piston wobble plate) are like the now smaller Sandens that we use in Freightliners. The Sandens are much lighter and take less power to push. The two cylinder Tecumseh/York compressors are still available. Sanden makes numerous sized compressors for different applications. I would suggest getting the serial number from a recent Freightliner (the last six digits is all you need-we use serial numbers for parts replacements) then you'll have a compressor that will be easily replaceable on the road if need be. Although Red Dot makes most of the big rig A/C's, they are also custom designed for that truck.
The A6 is the largest "car" type compressor you can get-although Sanden does make one that is about the same output as the A6. Good Luck, TomC

been like that since 1978.....and the new 4108 a 76 model has been that way since it rolled of the floor at Pontiac too.

Excellent! How many evaporators inside do you have and where are they placed? Good Luck, TomC

those are actually Coach Air, not house air

Factory mod/retrofit to replace the PTO powered big 3 Cyl Compressor

so that would be one Evap in the stock position with the stock Fan
