thx for your detailed explanation. i hope this my last question. looking at your pic of air intake, i wonder if i could just plumb the air intake to the rear turnbuckle area. its pretty big, and the door blocks it off from interior.
i am going to use the propane door, to vent exhaust. i decided to not use the propane tank storage, and will mount tank on jack brkts for the few times i winter camp.
If you have a slide in, the turnbuckle area would work well.
