man. you're sure wanting to spend the OP's money :)
I would assume that will not be an option since it's an existing house and that kind of mod would run well north of 20k as a remodel IF the roofline doesn't need to be touched. mess with trusses and cost goes up exponentially. . going from a 9ft to 10ft door keeping the height at 8ft which already fits is still a chunk but much more feasable when compared to the cost of a good trailer mover and 1 trip to the dr for a back spasm.
will be interesting to see next year what the OP does. that Kaiyen is a GREAT boat.....
