I just completed this method in person and thought I'd share...
I live about an hour away from the nearest VT DMV. Decided to just go up there today and try this, I was in and out within 25 min. All I brought was original title from seller made out to me on back, bill of sale, application and checkbook. I did not do the VIN verification. They made copies of everything and then handed me back the originals.
My bus is a 2002 which as of this year falls into the no title 15yrs and older category. I filled out the form very similar to Nate, top part with my info etc etc.
They had me fill out the private seller's info in section 3B, also the purchase date.
As Make I wrote 'Blue Bird' which they didn't change, Model they put TK (same as Nate's). I typed MH for motor home in body style which they didn't change, I had yellow as color as it is on the title, they said if it's a converted school bus you need to remove all the school bus stuff and it can't be yellow, I told them it's been painted black so they had me change it to black. Under the Trucks section I put Axles: 2, Brake Typ: HYD and Loaded Weight: 26000, left 'Empty Weight' blank cuz I do not know.
They noted on the side there's no NADA value so they charged tax on the amount I entered as purchase price.
Wrote a check for tax plus $76 registration, walked out with plates and a copy of the form as temp reg. and will get the rest in the mail in 7-10 business days. I could not have smiled bigger.
Thanks to all of you for this great thread, it definitely saved me a lot of headache! Hope my experience helps too.
