Most states do not allow 2 ball towing ( 2 bumper pull trailers ). However, most do allow the first trailer to be a 5th wheel and the 2nd to be tongue pull. This is my problem, I want to go to California to cruise the big dunes, but can't because New Mexico and Arizona don't allow 2 ball towing. I'll have to sweet talk someone into either letting me sleep in their motor home or hauling my buggy over there.
