With the rv conversion I doubt anyone would consider a dot check. Pass scales and let it be. there are many RV's out there much larger than yours though not as eyecatching. The original gvwr would be under 26,001 lbs and no air brakes or hazarduos materials involved non commercial use. should be no cdl, no logbook,no fuel tax reports,no dot number required. Have fun. Good your family supports your adventure.
