Hi folks: I have a 93 34 Limited and the original factory AC died the other week during our recent 100 degree weather here in Western AZ. In prep for my replacement ACs arrival I went ahead and removed the old one which is a Dometic Penguin. After getting the mechanical works off of the roof, I went to remove the plastic bottom pan and found that it was adhered with gobs of waterproof caulking essentially sealing it to the roof. I had to destroy the pan to get it removed and deal with quite a mess to get the surface prepped. My previous experience with AC units was that they were usually installed with a foam gasket.
Does anyone know if this was a typical factory recommended installation method instead of the foam gasket? Is caulking a method I should consider in the reinstallation process?
Thanks for the help......
