Ok one more time - NON-alpine owners, the parent company of Alpenlite 5th Wheels and Alpine Coach’s which was Western Recreational Vehicles, went out of business in 2008, so telling us to call the OEM is like losing all your teeth and then going to a dentist, that don't fix the problem. Plus, unlike most other coaches, alpines are all almost the same mechanically, for the radiators, CAC's and mechanical systems, yes there were a few changes, and modifications, but for the most part, and especially true from model year 05 to present, they are all the same with some sheet metal changes, and in 09 they moved the exhaust pipe to the other side of the coach because of the emission ISL425 HP engine installed in those coaches. They also changed the radiator grill in that model coach, it’s more rounded than square at the corners. But the radiator, CAC, and all that other stuff is in the same compartment in all models, nice, easy to work on, and if an 01 owner says “hey, I got this thing behind the radiator, and I cannot figure out what it is”, one of us has fixed it and will know. Now, if the problem is a propane water heater, maybe a refer issue, chime in, since WRV did not build those.
Mac's Radiators in Portland, Oregon has also fixed or manufactured new ones of these If my memory servers. Burke Morgan also might have one new, and Aubrey's RV in Yakima, Washington bought up a bunch of auctioned parts they also might have one. IF worse comes to worse, Cummins and Freightliner can most likely have it repaired as well. I don’t want to post Burke’s phone number in this public forum, so if you need it, send me a PM, and I will get it right back to you.
