It seems that the industry is slowly moving away from wood stud, fiberglass insulation and aluminum siding to the fiberglass skin, aluminum tubing, solid foam for wall construction. Both have their p...

After doing a bit of math, if my camper had Azdel in the side walls, it would be roughly 100 pounds lighter and have an R-value about 0.6 higher. That higher insulation value is only in the side wall where the least amount of heat transfer takes place.
I cannot see that the selling points of “2X the insulation value and 1/2 the weight of luaun” have any real value in themselves, especially since luaun is pretty light and has an R-value of about 0.3.
The rot resistance of Azdel may have merit, except that if there is enough water intrusion to rot luaun, the Azdel will probably have come loose from the fiberglass and/or the foam.
As has been said over and over, it’s the maintenance that makes the difference.
To find which is actually lighter, you would have to find the exact same camper with both types of construction.
