Prior to pulling my m35-m200-m146 combination, I called VA DOT, NC DOT, and SC DOT. They asked me how much it weighed, they asked what was in it, they asked if it was all mine, they asked if I was hauling anything for anyone else, they asked about lights, they asked about brakes.
All three said- It's yours, it's under 80k, it's not commercial, no CDL
I highly recommend you check with your DOT, and keep the names of those you talked to with you, incase a curious trooper stops and asks. I did stop at a weigh station in NC, just to make sure (it was the only one open on the trip down) and the guy was trying to sling his own arm off he was waving me over the scales so fast- aparently to him I was holding up the line.
Another thing to concider- say you get a dolly, and get there, and the brakes on the trailer are trash? what then? I definitly would not tow it if they didn't work with a dolly. You might be able to ease it off base to work on it, but that's taking a huge risk, you sure don't want to get in a wreck.
Just my opinions based on my experiances.
