I have a 2012 Winne. Vista 26P. I have been mostly happy but recently the bed broke. I figured, easy fix...right? You can't believe the mess I found. The bed surface was made from a very low quality wood frame. In fact the frame had broken during manufacture and had been stapled back together (giving it zero strength). The frame was covered by 1/8th inch plywood glued to the frame. ALL of the glue had failed and the plywood was basically floating on the frame. It was trash. The bed vertical support has broken where the assemblers put a screw through a knot in the cheap pine wood. The bed frame was separated at every corner and 3 of the 4 corners were broken and delaminated.
Appalling, shoddy workmanship by Winnebago.
I built an oak bed surface with 3/8 ply glued over the oak frame and insulated underneath (in the spare tire compartment). I reinforced the bed vertical frame and re-glued (with good wood glue) the broken knots and frame covers. I also reinforced the vertical frame with 2" supports. I added weather stripping where the bed surface made contact with the spare tire compartment to stop the smell of the tire from annoying my wife.
The fix was simple, inexpensive and took only a day. I am ashamed that Winnebago didn't do a better job on this critical component of the $100K+ coach.
When I trade this unit, I don't think Winnebago will be on my list of new coaches.
