I just remembered that my next door neighbor ended up mounting an electric winch at the rear of his garage, a straight shot from his driveway, and pulled the trailer up the driveway, back end first and just steered from the bow as the winch pulled the boat and trailer. Again, good luck on the logistics.
Just like Jeff said,but stagger ancored 4in metal pi[ies in ground for piviot points in the yard/driveway
Put a trailer hitch on front end of truck, just remove the ball hitch section out of the receiver when not using. Good place to get hitches that are good quaility and cheap is U-Haul rental centers.
