I have a 4Wheel popup slide in truck camper with a Dometic RM 2354, won't cool effectively using propane, I believe the problem is that the flue vent is routed so that exhaust gas collects behind the top of the unit. It has an aux fan that is supposed to blow the exhaust out the top vent (this is a side mount, no roof exhaust). I have seen online that some units can have the flue plumbed to the outside with an elbow, but I can't find the part online to do that. Two different techs have id'd the vent issue, but it is apparently installed the way Dometic specifies. It cools fine on AC (25 degrees), but on propane it warms up to 50 degrees, and if I don't run the aux fan the top of the fridge inside the camper is almost too hot to touch.
Any suggestions?
