Jamie, as I understand the bubble issue in the walls, this is known as delamination. Delamination is where water has gotten into the fiberglass and begins to breakdown the glass. In my case this is just the latest issue with the Axis unit. I believe that the Camping World in Bath, NY could not handle this repair and thus called in a Thor technician. Said Thor representative found far more issues with leaks and made the call to recall my unit to the factory. Based on the units history since date of purchase, September 2014, I do not hold out much hope for this unit being a product that I would ever recommend to anyone. Also, based on all my communications with Thor representatives I strongly do not recommend their product, at least this one. I do also own a Heartland Big Horn 5th wheel, which has been an excellent unit. Just a side not the Camping World in Bath, NY has been closed.
