MO Must be running a program currently.
Buddy of mine has a Dodge RAM 3500 Cummins power he uses for pulling his fifth wheel trailer, Licensed RV. He lives in Holts Summit N of Jefferson City MO, took the truck and a borrowed 16' trailer to Lumber yard in Jeff City, coming home got stopped as First did not have but a single 2" strap holding his material and had shifted, then got a $85 ticket for using a RV for other than RV use(Has RV plates on Truck to escape Driver license requirements and Weight Tag expense) In MO RV is $32, 24K weight tag is $100, both plus issuing fee at offices. His truck and Trailer loaded weigh in over 25000 so would have to step UP to Commercial 26,000 plates($130) and Class A CDL which he does NOT have.
IF they do not provision up prior to leaving and Drain all the tanks completely between destinations MAYBE could get under 24,000 License.
