I'm not familiar with the coaches but would it be possible to fudge 6" to 8" from behind the rear seat? Could you possibly build a seat back that could contain or at least fit around a spare?
I knew that was your coach I just didn't know how much room you could carve out inside and have enough leg room. If you stick with a skinny spare most of it might fit in the seat back. Maybe there would be room for a jack and some tools. What about space under or in the bottom cushion? With some of the new foam padding it might even be comfortable.
