I decided to go through the floor as it was the best option for me. Because I haul a motorcycle and 2 bicycles I was limited to where I could install this but it worked out great.
1. Trip to Lowe's to get a 6" to 4" sheet metal reducer. The a/c exhaust hose is 5 3/4 " so this adapter allows you to insert it in the deck plate.
2. Get a 4" access deck plate.
I cut a hole in the floor to allow me to install the deck plate. When not in use there is a screw on cover installed. In my case it exhausts the air into a boxed in area right behind the wheel well which is well protected from road debris and rain. It shows in the pics. I had to cut some slits in the 4" side of the reducer in order for it to slip into the deck plate which is a snug fit so no air escapes. The exhaust hose fits snug in the 6" side with no leaks either. When traveling all the pieces get stored in the overhead cabinet and the a/c unit gets secured to the wall. It all works great and I have less than $225.00 invested and still retain the exhaust fan in the ceiling for pulling hot air out.
Heading to the Texas hill country and doing some riding on my Indian Chieftain motorcycle --------- life's good!!!
