Has anyone heard or read any new laws for towing a trailer in Pa? I heard yesterday that I need to register my truck and trailer as a "combination". I always thought that they took the gvw of your truck & trailer added them together to get a total gvw (8800 + 7000 = 15800) then took the unlaiden weight of both truck and trailer (6200 + 2300 = 8500) subtract unlaiden from gross (15800 - 8500 = 7300) and that is what you are allowed to haul. The way I understood the guy is....... If my dodge 2500 has a gvw of 8800lbs and has an unlaiden weight of 6200lbs that means I am only legal to tow a total of 2600lbs. therfore leaving me being able to haul 300 lbs of equipment on my trailer. Im trying to be compliant to any new regulations but it seems that every DOT officer or trooper you talk to has a different answer. Does anyone have a clue as to what the law reads?
