Will sitting in a dinette instead of a sofa work for both of you ?
We tried this KZ floorplan in 2016 and after spending an hour in the dinette, we decided that spending two hours in it , would not work for us.
The sofa in our new Jayco worked out much better for us. At 27' no slide opposed to 24/25' with a slide were approx the same weight and TW , i don't find it to be a problem parking/backing the extra 2-3 ft.
Besides, we like having the optional 90 gal water tank for longer state park (no hookups) stays. The KZ floorplan didn't offer that.
