My dealer has been in business for decades, he even admitted that a really hot day can be enough to allow delamination to start! (glue separating from the luan)
Remember, everything is glued together, and in most trailers the luan is an actual wood based product - think flooring underlay but even thinner.
I agree, with all the issues out there you would think that someone would be trying harder to make this a thing of the past.
There are some trailers that use composites instead of the wood product but they still rely on glue to hold it all together.
Airstreams are a totally different take on a trailer and are skinned in aluminum. There has been some issues with the clear finish on the newer airstreams, seems that the use of a non lead based clear finish has been an issue in some cases. Count on parting with $5000 to refinish!
Seems us consumers can't win... Just remember, Rving and camping is not about the trailer but about the memories that are made. It seems that we live in a throw away society with a limited life expectancy for everything...
happy camping (with lots of memories),
