Nice crane setup and bolt down. Good to see the rubber mounting. We had trouble securing a long mod roadster because the trailers flex more than the race car, and locating points change length on segmented highways.
Planning a new trailer myself for the next build. I use doubled snatch blocks, currently, to slow down the action during alignment. Will go 4-part reduction next due to lift battery drains too fast when winch slows down, but runs forever when its not.
Beautiful car and concepts!
P.s. Drown the winch cable in LPS3 before you get on the salt. The stranded wire does capillary action from salt anywhere on the cable and any moisture at all. The corrosion goes all the way to the drum overnite. I also need to LPS1 the heavy wires to the winch next time...same problem with stranded copper wire. Thats why my ocean sailboats had solid copper wiring. Hope this helps save you money.
Also, if you unload on a slope or trailer unlevel you need a cheater bar off the back of crane post so guys can control the swing. I often have a ratchet rope rigged if it looks spooky, to keep it from getting away.
