Bill:

Not sure about all states, but here in MO the tow vehicle must be licensed
for the weight of the tow vehicle plu the towed vehicle.  Thus, I have my
Ram 2500 licensed for 18,000 lbs to cover the weight of the truck and travel
trailer.  I have also "heard" that this requirement is also very "loosely"
enforced which accounts for the many folks you see who don't have the
required plates for their combo.

Hope this helps!

Not legally. If your stopped the fine will be for driving out of
registration class, and you will probably have to get a new registration
with the higher amount or pay to have the trailer towed away. Another
thing to keep in mind is the GVW of the tow vehicle. If your trailer is
above that as well as the registration you will get at least two
tickets.

Talk to some of the folks who have been towing into Florida. They have
been finally taking the laws seriously in regard to registration and
towing capacity. They have also been impounding vehicles if your vehicle
is rated for more than your drivers license class is legal for. They
give the vehicle back when you or someone you designate shows up with
the proper class license to drive it. Many states look the other way
EXCEPT in the case of an accident.

Personally I don't like the way that folks can just walk in and buy one
of the huge motor coaches and drive away with it when the largest
vehicle they have driven was a Geo Metro. Or the ones who just picked up
something like a 3500 dually and the new 40 foot trailer without ever
towing anything before.
