We need to clear the air a bit here.
Some winch basics for the truck part of a truck camper:
1. The commonly held formula for applying a winch to a rig (of any kind) is,
the winch pull rating should have at least 1-1/2 times the weight of the rig. So my 10K pound truck camper needs at least a 15K pound pull winch, and that's what we've got.
Remember that the larger the winch capacity, the higher the rating of the bearings, cable, roller fairlead and winch plate are.
2. The winch attachment hardware should be appropriate to the winch rating. I found short of a new winch bumper with correct rating, my Warn 15K had only one option; the Warn carrier.
3. Many commercially available winch carriers, especially those that plug into a receiver hitch are maxed out above 8K pounds, which automatically cuts them out of the equasion for a truck camper. The only way I would use one of these, and I have, is if you include a snatch block, extra length of cable with safety clipped hooks, a tree saver, and a Cat Choker and do only straight line pulls, which are rare.
4. Using my pickup without the camper to winch something heavier than the truck has always been problematic unless I 'dead man' the truck, which is to say; tie the truck to something heavier lest it slide along toward the heavier object you are trying to winch.
5. Is there such a thing as too much winch? Not for a truck camper. It's the weight (from 10K to 14K pounds) that will stop 2 or 3 jeeps with winches in unison to budge your TC. Most people do not need a winch because they never get that far off of pavement. Many of you are jeepers types who have been winch users and have broad knowledge and experience of how and when to use is it with a wary eye on what will stop your rig before you need it. I've had 6 or 7 winches of all kinds, and maybe 500 pulls of one kind or another and actually wore out my old Warn 8K using it more that 300 times until the bronze spur gear had no teeth left. Knowing what i know about winching, if I did not have a winch, I would be much more cautious on the routes I take without the winch backup and the technique to use it.
6. The limiting factor on having a winch that moves from front receiver to rear receiver is the weight. How heavy a winch can you lift? My Warn 15K weighs 150 pounds. I'm not up for lifting that. Also, there's the matter of power cables. No. 2-4 cable is heavy and expensive. You must have long cables to make it to the rear.
Here's my current winch set up with a welded on front receiver hitch, 26K pound 'D' rings and added cromoly tubing and a radiator saver:
Here's ctraveler2's Chinese winch on his custom built carrier. It' not going break. Note the holes for the 'D' rings and brackets attached directly to the Ford frame horns.
