I did say that private motorhomes are being allowed to operate well over the 26, 000 lb limit, and yes, those chassis are mechanically identical to a commercial truck.thats only half true, the CDL comes in to play for hauling commodities, you can buy and drive a full fledged 18 wheeler with a 53 ft trailer for your own amusement if you want to,,, i dont want to get into my feelings on this matter so i'll leave it there.
U-haul, Ryder, etc. all spec their largest trucks @ 25,999 lbs or some arbitrary figure so they can be rented to the general public.
I still think that operation a 26k lbs+ truck that is not registered as a RV without a CDL would be considered illegal, regardless of whether it's for hire or not. Guess I'm going to have to actually look the stuff up, though.
Sorry about the thread drift, doesn't have a lot to do with the weigh station question.
