Has anyone been stopped by D.O.T.

In the past it's been a state tax issue as far as the states are concerned. If you have the plates and registered weight structured so you're covered, the state was happy.

I see this posted on rv websites quite often.
My state as others do not have any type of weight to register our trucks at. Nor does my state care how much weight a truck (the size being discussed) from another state is registered at.

Some may remember the long email from a CA DOT officer to I think a RV.net member that had this question and answer; *its long and snipped for length*

October 14, 2009.
Q: “Many of the owners travel over their tow vehicle GVWR and /or
GCWR. Are there any state laws against this? Or does the owner just
take the risk if they wish?”

A: The California Vehicle Code (CVC) does not contain a law that
specifically limits the amount of weight a vehicle may tow based on the
towing vehicle GVWR or GCWR. There are, however, laws that limit the
amount a vehicle may tow based on other criteria.
(snip)
Section 1085(d) of Title 13 California Code of Regulations prohibits
the loading of tires above the maximum load rating marked on the tire,
or if unmarked the maximum load rating as specified in the applicable
Federal Motor Vehicle Safety Standard, or in a publication furnished to
the public by the tire manufacturer. This would most likely happen in
the case of a pickup truck towing a large fifth wheel travel trailer, as
those types of trailers tend to transfer a larger portion of their
weight to the last axle of the towing unit causing that axle to exceed
the tire load limits.

I trust this has adequately answered your questions. Should you desire
any further information, please contact Officer Ron Leimer, of my staff,
at (916) 445-1865.

My state not having any weight registration for a non commercial vehicle simply uses the trucks axle/tire load numbers....same as CA.
