It is substantial, I think I could get by without the turnbuckle, but it's there. Winch is a Dutton Strongarm SA9000DC. It powers both in and out. I had another electric winch for my Catalina 25 sailboat. The winch would pull it in but one had to free the winch and let the boat roll off; quite spectacular. Swore I'd never get one of those winches again..
The Dutton winches are made in the USA and the total cost was under $600, $500 for the winch and $100 for the rest. I put it on after a big session at Lake Powell where the water was down and I really had to winch a long way. Didn't want to back it in until the rear axle was under water, cause that really destroys them. Stopped several times to rest, Finally got it on. Came home and bought a winch.
