Ed Pruss Just saw your autocrane,I have the first generation autocrane,only thing power is the actual lifting. Have used it for all kinds of stuff,is good for about a ton. Mounted mine higher at the back of the cab,learned early on with your nose downhill,you pick up something heavy it will swing around and kill your fenders upfront. Gin poles get crown pully up to 13 ft. 6 hook hangs right at tail roller. Your GMC looks good,doesn't hurt to use em,had big fun with winch trucks for oh 60 years I guess.
