A few observations.

Lettering "Not For Hire" on the motorhome, tractor, etc. and keeping all the racing decals and company logos on the trailer goes a long way to not getting pulled over as a commercial vehicle. Also, a vehicle plainly marked "Not For Hire" should be given a break on the registration fees, since they are not being used to generate income. Whether or not you actually make money racing is an IRS issue, not the DMV's.

As to common laws - does anybody really think a 90' rig that would be fine out West belongs in the mountains of West Virginia? Individual state roads and geography dictate safe lengths of vehicles.

Lobby state Department of Motor Vehicles to release a 50 state guide on what the laws are - the better people are informed, the safer it is for ALL drivers.

I don't have a problem with motorhomes, carhaulers, etc. needing the same inspections and driver CDL's as any similar sized rig - all 70', 40,000lb vehicles should have the same safety and drivers requirements, no matter what they carry. They should least have yearly inspections and updated license requirements.
