1. The dealer is not an idiot--his so called tech is
2. The fix to the original AC was to replace the mount gasket as it was compressed too much from install (or continued tightening from the original complaint). This causes the mount pan and drain pan holes to be compressed and blocked off by the rubber roof. COMMON problem on RVP AC units from Installers and service techs that continue to tighten the mount bolts without realizing the problem with doing that. Once the gasket is halfway compressed you REPLACE the gasket to prevent water intrusion inside
3. WARRANTY---RVP and Dometic pay Labor and supply the New AC unit. BUT, we are required to remove the Data Tag label (has model and s/n) and send this back with the warranty claim. That means the AC should not be sold and if so, there is no model number or Tag to ever get any warranty help.
4. I find it hard to believe that RVP supplied a NEW AC for the OP's original complaint. RVP knows what I know and posted here. They would have required the Tech to verify Gasket and mount. RVP would have paid for a new gasket under warranty. Doug
PS, THERE ARE 2 DRAIN HOLES ---1 ON EACH SIDE. NOT weep holes, drain holes
