That certainly sounds like Michigan is one of them.
I missed the latter part of your question.
I don't know the process in Michigan but I did find a bit regarding converting a truck to an rv in Michigan:
"This may be hard to believe, but the registration and licensing of my 2003 Peterbilt 379 conversion was almost a "pleasant" experience in dealing with the Michigan SOS.
When I first bought the tractor from a local truck dealer, I went to the SOS office and asked what I needed to provide in terms of documentation for my vehicle to be registered as a motorhome? I was told I needed a certified weigh slip, plus proof of insurance.
As it took me about three months to get all the preliminary work done prior to weighing; drop the front axle, add the 16' dry box, add the split 120 gallon fresh/gray water tank, and a few other things.
I got this all done, went to a Cat scale and weighed the beast: 21,400 pounds. Also got some RV insurance from Progressive. I took all this in the SOS's office, and just happened to get the same lady behind the counter who helped me three months earlier. She said, "Oh, I remember you!"
It was a smooth slide from then on, and in about two weeks my new title arrived in the mailbox with these words across the top:
P E T E R B I L T M O T O R H O M E
I was a happy camper, literally!"
