Thank you Rigmover.....I think you are probably correct even in the US that it depends on what state and what mood the DOT is in that particular day. They aren't going to bother a dually with a travel trailer because it is exempt and they don't have time to deal with them, but of course there are always the horror stories you occassionally hear about. Now, with having your Peterbilt pulling even a 5th wheel travel trailer, like you said GVWR might cause more of a rucus because it is a unit capable of towing commercially, and with todays "post 911" world, anything is possible from a DOT agents eyes. It would be interesting if anybody else experienced anything. I also wanted to ask since you have tandems, did you need to slide back the 5th wheel on the tractor to clear the undercarriage of the trailer? Thanks again....tr
