The trailer has a hydraulic operated upper deck. Remove car, lower the deck with the boat on it's own trailer, shove the boat/trailer off using the loading winch to hold it back. Carries it's own wheel ramps including a "c" channel for the prop wheel. I drove from Forked River NJ to Paxton Nebraska (with a side trip to Rushmore) to pick it up. They do have an option where the boat is on a cradle on the top deck and you dunk the whole trailer. Didn't care for that idea. Once in camp I can trailer the boat to the water. The Built-Rite is robust and relatively light. A hydraulic ram pulls on stainless cables which do the lifting. The cables are terminated with Sta-Locks.
The wheeled deal is a "Trailer Toad". The guy that makes them calls it a trailer hitch extension. It mounts solidly to the motorhome's hitch, has a steering axle, and takes the full tongue weight of the trailer, which I have had as high as 1500 pounds. For my own peace of mind I changed off the original wimpy 5000 pound hitch for one rated for 16,000 pounds. Overall length is 67 feet, plus the stern section of the boat and mast. Right now that's about 6 feet but I could shove the mast forward but if I forget I'll blow out the car rear window. Motorhome, 40', toad 4', trailer 23', overhang 2' to 6'. 69 to 73 foot. Not sure how legal it is, but I've seen motorhome rigs consideally longer.
The missing motorcycle is a 1979 Yamaha SR 500 thumper. I'm doing tires, chain and sprockets, front master cylinder and a few other odds and ends. I'll have it ready for the winter trip to warmer weather. This whole rig is about getting out of the cold and having all my toys along. Just my luck my girlfriend prefers cooler weather. I just have to figure out how to realign her thinking.
