Air Conditioning Leveling on Install
I just received shipment of a couple of new Coleman Mach 15 units to add to my toyhauler fifth wheel, one for the front bedroom and one for the garage. And I'm replacing and updating the ducted unit in the next couple of weeks. My Jayco is a 2005 model and I've been having to work on the main unit now fairly often.
Other than wiring the garage unit on a dedicated exterior circuit that install is fairly straight forward although I need to figure out if I can use the wires that went to the vent fan to add a thermostat since that unit will be too high to reach the controls on without a ladder.
But my concern is the bedroom unit. The roof over the front bedroom slopes towards the front end of the RV. Using a four foot level I measure a drop of two and a half inches. Reading the instructions for the Coleman unit it warns that the front of the unit needs to be higher than the rear if not level and if the roof is sloped in the wrong direction I should build a leveling frame to fix the problem. But I don't really want the unit to be sitting up off the roof. That will make wheather sealing a problem and it will be a place for leaves and trash to collect under the unit. Coleman advises not to mount the unit backwards for some reason, maybe to protect the coils while traveling.
Has anyone else run into the situation and worked out a solution? I'm tempted to simply flush mount it and ignore the instructions rather than having it jutting up out of the roof that much. But I don't want condensation dripping back into the unit either.
