Bubbles in tile floor

[smjcolsga]

I dunno about that. Can't predict the future, but my guess is that it will eventually spread. The repair place I took it to today for the wall issue, said they didn't want to fix the bubbles. All they would be able to do is patch it, and it would be a big ugly eyesore. I'm going to research some more on it later, but right now my main priority is the loose moving wall.

Insofar as the 'loose wall' is concerned, an understanding of how Thor changed the construction method may help visualize what the problem might be... all LL trailers were originally built around what is essentially a welded-together aluminum cage, it got its strength from being a rigid structure despite its light weight. The aluminum floor support beams were welded to the frame rails ontop of which were welded the aluminum flooring planks. Side walls (and roof, if appilcable) were welded to this base, making a solidly built structure onto which floor and wall coverings were applied. I imagine that labor costs for skilled welders to take the time needed to build these was a significant factor in the total cost of those units as each one was essentially hand-made. New laminate floor and walls are made in-house and are all built up on large presses before being used to assemble a new unit. The welded-together aluminum cage is no longer there so floors and walls are screwed, glued and/or bolted together at points using internal panel 'stiffeners' which are just square aluminum tubes placed in the laminate cores before it is pressed. These aluminum tubes aren't welded together or even joined to one another, at least from what I saw in pics, but are just free-floating and held in place by the glue and outer laminate sandwich layers. Bolted up into floors and walls, you can imagine the stresses placed on these internal stiffeners as the camper is subjected to twisting forces and loads.

when I first read about the new floor system along time ago that was my first question. How the heck are they going to hold the trailer together. It doesn't take a rocket scientist to realize the lack of strength in " laminated floor". I don't care what there response is the whole thing is stupid.This is so disappointing to see this happen. I hope you get this all resolved.

We have a 2016 16TBS and just noticed some floor bubbling in the area in front of our fridge.  Our floor has the brown wood grain look.  Given our unit was built in 2015 it should have the better quality construction.  Any insights as to what floor materials we have and a fix?

You can determine flooring type by looking up at it from under the camper. If it's aluminum, the wood grained laminate on top may have had something spilled on it that damaged it? Best fix might be a carpet or throw rug covering it up. Removal and replacement would seem a monster job!

Yes it is aluminum (tongue and groove) subfloor from underneath.  Thanks
