Jerry,
Given we don't have a slideout, I cannot measure myself. Get out your tape measure and see if my captain seat dimensions x2 below will work.
With armrests folded up, it measures 25.0" wide (the widest point). 1/2" less when folded down. If ordered without armrests, it would measure 20.5" wide. You will also need to consider some space in between, and also swiveling action if that is a requirement. If you mount them on NON-swivel pedistal bases, maybe you could get enough dead space in between two seats to add a small dinette table.
What is the interior width open area of both the older and newer (with fridge) slide outs?
