Thatguy,
I trailer my Lancer 25 on a regular basis. My boat is only 4000 lbs loaded where yours is over 7000 lbs. But, the right F350 and a trailer, and you can haul that all day long. Easier said than done, but if you could rent or borrow a trailer and your buddy had a pickup (and you're in the south!) you can save a wad of cash. There is still the sling and stepping fees, though.
Good luck with the move.
