I had my XD9000i on a multi-mount for years. Used it on the rear of the Sonoma, and on both ends of my Cherokee. Not having the winch mounted all the time on the Sonoma was nice, but the Cherokee was a dedicated offroad rig, so it was more about being able to winch from both ends, which was also nice, though I'm not sure I ever used it on the back, just carried it there. It worked out well because I could take the winch with either vehicle. When I ditched both and got my current Jeep together, I plopped the XD on a winch plate and bolted it down and haven't looked back. Of course, I also have a winch on the front bumper of my truck, so I always have a winch with me.
My take on winching backwards is this: I don't drive into stuff that looks iffy unless I have a strong desire to get through. If I drove into something where winching forward isn't an option, and there's nobody else with me to pull or winch me back, I've failed miserably, and deserve to have to bust out the Hi-Lift and get to work... I did have to winch mostly sideways once, when I slipped off the road, but so far haven't had to winch backwards. (Knock knock)
For the Comanche, I'm going back to having front and rear receivers, and a small winch on a multi-mount. (Badlands 3500 that I already own, actually...) That will be plenty of winch for the "trouble" that this 3500lb truck will see out here in the desert and mountains. It doesn't weigh much, and I can also use it anywhere I can plug it into a receiver. (Back of the other vehicles, ATV, Trailer, etc...)
A lighter winch on a lighter receiver should prove handy.
