I have used Allure in my seasonal Cherokee trailer. It's not recommended for RV's.
If it gets to hot or cold the adhesive that holds the seam together fails to do so. Where I had to force it to be together the glue would let go. Where it was in a relaxed state it seemed to do fine. I made sure it had room to expand and contract for hot and cold. The vinyl that was in it did not like -45F temps and split. I have had it in there for 3 years and plan on putting it my Wildwood as well.
There is a Allure that snaps together that might be better, but I have not used it.
I have no idea how it would hold up in the AZ heat. My TT the problem is extreme cold.
