I read the thread below, the whole thing, and some other threads here about Vermont registration. The one below is the one I followed to register my bus in Vermont. Once I read through it, understood it and spent some time on the Vermont DMV site looking at the forms I needed to complete I was ready. It was fairly easy, and when I filled out the Vermont forms I specified motor home and that's what's on my Vermont registration.
Just remember, Vermont wants your money so they don't want it to be too difficult to do.
