I will disagree with aluminum siding. I own 2 TT with aluminum siding and not a good choice in hail country. The one on the seasonal site is not in hail country and is ok. The other I have in Kansas to get some work done. Last Friday we had a hail storm and the door side has some damage. Fiberglass takes hail very well withot damage. I have found fiberglass trailers to be quieter as well. Fiberglass also is easier to heat and cool, less temperature fluctuating.
I have owned both and fiberglass is superior in my view. Go look at high end 5th wheels and see how many use stick and tin construction.
There are some advantages to stick and tin. Lighter weight, cheaper to build, easier to repair, does not chalk as bad in the sun, more affordable to purchase.
Fiberglass- More resistance to dents and hail, easier to heat and cool, quieter inside, and my insurance gives a discount for fiberglass.
Welcome to the forum.
Insurance will cover damage from hail, in my case 500 deductible. Would have to replace the side of trailer that received damage.
