I have a 4 ton come-a-long, 20' of chain, 150' of cable, about 90 feet of straps, and didnt have enough today when I needed it! drove into a swamp field with a hidden hole that grabbed me. Finally dug my way out and plowed backward just enough to make all my gear reach and ratchet winched my way back out of the swamp! A come-a-long gives somewhat more reach than a hi-lift. Mine reaches about 6 feet and can be undone from the snatch block for about 10 feet of reach at half the pulling power.
Gotta get a wicnch myself. Thinking of about a 3,00 lb model on a reciever mount to use front or rear. If 3000 lobs isnt enough pull then I can snatch block it and double the pull to 6.000. If thats not enough then I can still throw the come-a-long into the job for another 4 tons of pull. If thats not enough I hope theres a nice H-1 Humvee around somewhere!
