Dougherty and Associates was listed on the South Dakota DMV website for RV insurance.  I emailed them and got a reply a few minutes ago. "Yes, we do have a company that will write the truck once the conversion is completed.  Also, the conversion has to be done by a company that is specifically in the business of truck conversions." http://www.doughertyassoc.net I've never seen anyone reference this company on the forum.  FYI.
