It all varies so much from state to state...
For instance- here we do all the tag and registration at the county tax collector's office, not the dmv.
Just guessing here, but I think due to their sizes they *may* not require cdl's. I dont think the tag people care much about who is driving or who has what license. Here as long as its privately owned nothing really requires a cdl.
I didn't get a tag and I don't have a cdl and I drove mine 800 miles home. Bought it from an online auction, pretty much sight unseen. I called the school board who owned it, and the sweet little lady who handled those kinds of things there insisted that I would love the bus and that it was well maintained and roadworthy. She even suggested I drive it without the tags!
I'm not saying to do what I did, but I'd do it again...
Check the dmv site for wherever you'll be tagging and titling it.
Above all else- GET INSURANCE FIRST AND FOREMOST.
