In Florida they ask for a value and if one did not build it themselves
showing cost for materials, they ask for a bill of sale for the
trailer. They take the citizen at his word and let a reviewer look
over the paperwork later and do a float test. If they are suspicious,
one could be called apon to prove the value at a future date, checking
for tax fraud.
The value you claim would have to be way out of the ballpark to
attract scrutiny since so many DMV applications takes place per day.
The story must be reasonable.
The seller could be contacted.
Glad you don't pay 6.5% sales as we do in Fl.
