I've seen online ads. They pay by the mile/km one way from the factory to the dealer. The only requirement is a CDL and a diesel truck. In my area the dealer arranges and pays for everything. Not sure what they'd pay for smaller TT's but from what I saw the 14 hour drive would pay nicely. I could never tow a fiver without upgrading to diesel.
I'll agree, the pay does sound nice, but you've got to remember, that is only one way, you are deadheading on the return trip, unless you are lucky enough to find something to pull in the direction you are needing to go. Also, there are some expenses to take into consideration, fuel, meals, maint. & upkeep on the tow vehicle, insurance (company may take care of that), someplace to sleep on the road. From what I've heard a lot of these guys really don't make that much money, but there has to be something there or they wouldn't be doing it. Also, from what I understand the good ones are on the road all the time. I've never talked to someone who is a transporter, so I don't know for sure how things work. This comment is probably as reliable as anything else on the internet, and just my $.02 worth.
