If Thor brought a European Hymer to US/NA, they’d have to make revisions for our market. At a very minimum, they’d have to add an air conditioner and generator (or equivalent). These two should add no more than about 300 pounds.
In Europe the 3,500 kg RV Class seems common, which is about 7,700 pounds. Adding A/C and generator brings it up around 8,000 pounds.
By comparison, we don’t have many motorhomes (except for small vans) that only weigh about 8,000 pounds. Most of similar size start around 11,000 pounds. So why do our motorhomes weigh so much more?
I can only guess, but my point is that if significant extra weight is added, they may no longer be able to use the same light weight and fuel efficient chassis.
