We have a 29n we bought new in 06. Originally we bought this trailer for weekend and summer trips but now we stay in it for the full winter as snow birds.
The biggest issue I we had was the lack of counter space in the galley, and limited storage. We never used the dinnette and it always felt like it was wasted space, uncomfortable and just kind of a waste.
Second of concern was a growing soft spot in the floor in front of the galley(common I guess to this model) which after numerous inquires here offered little or no feedback as to a repair method.
So we opted to remove the enite dinnette, reinforce the floor and add more storage and counter space.
First after removing dinnette( a feat that took all of about 30 minutes) I cut out the linolenum and then installed a 2 3' x 4' 1/4" diamond plate aluminum sheets over the soft spot. Theese sheet were fastened to the exsisting floor and screwed to the crossbraces. The sheets span the distance between the frame memebers.
We then installed pergo laminate floor through out the trailer..
New cabinets were installed in the former dinnette area a base cabinet was installed on the wall by the bathroom which adds two drawers anda large storage area underneath. It also added a 48" x 24" counter. a 32" cabinet was added under the window over the wheel well. This cabinet is topped with a counter just below the window. On side behind the entertainment stand a desk/work space was added with storge underneath and a pullout shelf for computer use or DWs craft work.
The new floor allows the slide to function normally and the entire floor is much sturdier. The entire remodel added about 150 pounds to the dry weight but make the RV feeler much bigger. Plus it was definetely cheaper than a new !!!
