Replacing sofa bed and recliners

We have the same model trailer as you have. We bought La-Z-Boy recliners and put two of them right where you suggested. Fit great and are very comfortable. We seldom have anyone on the airbed but those who have been on it said it was comfortable so maybe you have too much air in yours. In any case, we put that in the back under the big window but it would not allow the slides to close. Missed by about 1/2". I took off the metal brackets that hold the side curtains in place next to the big window and that gave me about 1" more inch and now the slides come in just fine.
