Here is the link where I got my info from: 2011 Driving Laws for the US and Canada
Not sure if the laws have been updated since this was written
but as much as I travel I would have to go around states where triple towing is illegal.
It makes no sense to me why RV laws change from state to state, after all aren't they designed to travel in...
Maximum RV width 102 in.; maximum motorhome length 45 ft.; maximum trailer length 40 ft.; maximum RV height 13.5 ft.; maximum combined length for two vehicles 65 ft. Triple towing is illegal
. Riding allowed in truck campers.
RV Safety Requirements:
Trailers over 3,000 lbs.: trailer brakes, breakaway switch and safety chains.
State Driving Laws:
Wipers on/headlights on. Right turn on red allowed unless posted otherwise. At least two riders for carpool lanes.
