Thanks for the information and links, Roy.? I plan to make some mods to my HB9000, but am considering options.? The mod explained in my first post, above, involves fabricating ducts out of thin plywood and then strengthening with fiberglass.? I have also reviewed another creative person's mod that involves much less fabrication.? Attached are 3 pics of this modification.? I am not sure which of these I will try, or if I will try to come up with another option.? My 2021 Expedition Offroad has 3 vents, rather then the three in both of the mentioned modifications.? So I will have to make minor changes to support 3 vents.? I might put 2 vents below the dormer and one to the left (as pictured above) to go over the head/foot of the sleepers.
I any others have suggestions for heat pump mods, please chime in!
I am continually amazed at the ingenuity and creativity of Aliner owners.? I wonder if the manufacturer spends any time reading these posts to find future improvements?
Thanks to everyone for sharing your vast knowledge of camping in an A-frame as well as making improvements.
