I am in the middle of doing something similar. I was inspired by Blueloue69 and Ditter's posts in this thread:

As a result I investigated the Rec Pro Charles family of wall-hugger recliners and discovered I could fit the 70" double model with a 12" console in the middle in my trailer (with high probability). You might be able to fit the 80" triple or the 80" with the drop-down console in your trailer.

I have attached the drawings I made to convince myself it would fit. A few notes are appropriate:
1. The only drawings that are truly to scale are the ones of the sofas and the ones with the sofas inserted onto the floor plan.
2. On the large drawings the scale is off by a factor of 2. Divide any dimensions by 2 to get the true size.
3. For the recliners, the solid lines represent the dimensions with the recliners upright. The two sets of dotted lines represent the two reclining positions.

My trailer has two battery compartments, one on each side that intrude into the floor space about 10 inches but are about 1.75 inches off of the floor. There is a wire chase made out of wood that runs between them that sticks into the room a few inches. The Charles family of recliner sofas require the top of the headrest to be 3" off the wall when upright. In that position the rear frame of the recliner at floor level is 9" off the wall. I believe it will slide under the battery compartments an inch or so with no problem, at least in my case.
This information is worth what you paid for it. Use it as a guide to make your own decision.
