I have not studied the new trailers .
I own a 2002 Komfort 21T and a 2002 diesel GMC extracab short box pickup both ordered new . I have no need to look further . Both have held up exponentially better than their predecessors .
The Komfort has CORRUGATED PAINTED ALUMINUM SIDING .
It still shines just like a full body paint motorhome .
In 2002 the aluminum sided trailer was 400 pounds lighter than the identical " smooth sided fibreglass " trailer , which was not full body paint .
Komfort built that 21T on a 6 inch tall steel frame , it was 7280 # gvw on the axles with a light weight of 4800 # and a typical loaded weight of about 5300-5500 #.
We only have 2 lane US hiways here in the Cascade Mountain Range and I wanted a trailer that handled very well on 45 mph curves .
I opted for the 400 # weight savings for that reason .
I wash the corrugated siding after every campout with a 10 " soft bristle brush on a 7 foot handle . I use palmolive soap in a HOT bucket of water ,
My motorhome had the smooth sides so I know I could wash faster with the smooth sides .
I store under a 3 side shed . My 2002 Komfort still looks new , has had no issues with delam or denting .
