Greetings! I'm new here so hopefully this is the correct place for my topic....
I have a 2001 winnebago ultimate advantage. The dash ac doesn't now cold air and I need help finding the part number for the condenser. I have help from a friend with a truck garage, but I could really use part numbers to locate the proper condenser.
 
Nate what caused you to decide the condenser coil required replacement?
A cheap test is buy a can of refrigerant at Walmart and fill the system, then observe results.
Call Winnebago with your VIN to get more info on the A/C system, brand is necessary to order parts. I think
Winnebago used Evans Tempcon dash air. Even though they are out of business (Jan 2023), parts are still available.

My condenser looks pretty bad. Has some rotting. I had my truck garage replace the ac compresser while they were in there replacing other pullies. I didn't want to do all of the work and leave the condenser to leak. My plan is to work our way through the ac system and hopefully have a much nicer reliable system.

The supplier was probably SCS Fridgette not that it makes any difference. When I overhauled the Horizon's dash air I was able to source all of the parts I needed after some Interwebs searching.

The condenser "looks pretty bad.." has "rotting.." - I'm not sure exactly what that means. Aluminum doesn't rot, it does corrode under some circumstances. So the assumption is you or someone else discovered the condenser core is leaking?

I forgot this; when we bought our MH the dash air did not cool, but rather than throwing money at the problem right-away I bought a large can of R134a with the gauge and filled the system to the full mark in the gauge. that same can of R 134a today is $40.
That must have worked because that was in 2013 and it has cooled great to this day.
