Danger, Will Robinson, danger!
First, it's a deadhead run. No $$ to get back to Elkhart.
Second, the new regs on trucking REQUIRE you to stop and get a room after a certain amount of hours. You cannot rest in your truck.
Third, It's a competitive market and buying a truck JUST to make runs for RV World is not a wise decision. What if they decide that this program isn't worthwhile and shut it down?
Fourth, I believe a CDL is required.
Fifth, the bookkeeping can be onerous with regards to road-mile taxes in different states.
Sixth, you'll need a fiver hitch AND a class IV regular hitch with a WDH so you can pull whatever they want you to pull.
Check out car transporters on YouTube. A lot talk about what they have to do now with all the new regs.
