I agree with Jon. I pull a trailer and the combo is 75 feet overall. I have never been stopped of even questioned at toll booths. I make sure all the lights are in proper working order as well as the brakes. I always try and drive defensively and courteously especially when towing. By this I mean always using turn signals especially for lane changes. You will find that the truckers appreciate this and will signal you when it is safe to change lanes.
Tully,
I prefer the flat nose also for the same reasons. Make sure you get at least 10000 GVW and what is called an RV tongue. Mine is 54 inches long and helps to keep you out of the jack knife jackpot
