If you care about your Model T ....
Spend the money on an enclosed trailer.
Model T's are fragile vehicles by design intended to be driven
at 40 m.p.h. top speed - not at 80 m.p.h. on the freeway.
Open cars in particular can sustain top bow damage even when
the top is retracted on an open trailer.
Closed cars can have the fabric - trim - sheet metal separate
when hauled on an open trailer.
That is why I have an eight foot tall rear door ....
I just dropped off this 1922 Model T Speedster at the MTFCA Museum
this morning in Richmond, Indiana this morning.
This makes at least (5) Model T's I have safely transported for the MTFCA over the years.
All have been in enclosed trailers ....
In addition to wind damage - there is
hail from the sky and debris from the road that no rockguard
on an open trailer will protect you against.
