Thank you all for your support for me; I finally started a thread of my own.Continued apologies to those whose threads I piggybacked on, so I guess I am now graduating to elementary BBS school.For those whose advice I am reading, I must stay underneath the coach with my A/C equipment, and I have one completely empty bay left in which to do this, and few other hiding places. I can plumb or wire anything I need, in order to make whatever system I install to work, so give me any information that pops into your minds, and I will sort through it all. Without the combined knowledge from this site, I might make a serious error.I am still trying to figure out if evaporators are directional; can I stand my unit on its end and still get it to work? I have two possible locations to reinstall the factory evaporators (if I am to go back to the original equipment), and one location would require the unit to stand on end.I can place one of my two condensors behind the bumper, with few modifications, so that part will work. The other is still in place.I still have the original compressor in place. Iwas about to remove it and find a smaller one for a driver only system, but I am going to wait until I get more input from you-all.The more I learn, the more I able to get into this project, my ninth coach. This is the most adventurous project I have ever tackled, and I have to get it right. I have lots of onboard power, so the cooling system size is open ended. I just need to know that when this cooling system is done, the interior will stay cold enough to hang meat, no matter where I am in this great country.So keep those cards and letters coming, and I will have a thousand of you to thank when this coach is travelling through temperatures over 100, and it is no sweat.
