Another idea would be somewhat of a Hybrid solution
Have the proper
trailer built and then hire an Experienced Driver with the Proper tractor or truck to tow it via USHIP or something similar.
That way it's their responsibility for all clearences,hassels and
insurance
and you save considerable wear and tear on you own vehicle.
You could even drive the pilot vehicle if one is needed for further
cost savings. When I bought my 19' Mariner having no experience
driving with a
trailer this is what I did. Didn't fancy a drive from
Long Island NY on the
Long Island Expressway then over the Throgs Neck Bridge, Cross Bronx Expressway,George
Washington Bridge and then thru most of
New Jersey to the lake where the
boat is now. The fellow showed up with this Giant F350
Diesel, checked out my trailer I checked out his
Insurance and two hours later my
boat was at its new home. Took alot of agnst out of my life
