I'm late to the party and haven't read everything. No rear mount winch for me.
No front mount winch for me either. My F-100 has an 8274 mounted in the front bumper, but it hasn't had anything on the spool in over 30 years. It'll probably need to be rebuilt before it'll be usable. The winch is staying, but it'll be rebuilt along with the rest of the truck. Still probably won't get used.
I've got a 5k badlands mounted on a hitch mount. Swapped the steel cable for a rope so it's a little easier to handle. It's only been used once or twice to load a dead vehicle on a trailer. Still need to set up a control box for it, so far we've used jumper cables straight from battery to winch posts. Works, but probably not the best idea.
it's hard to use a reciever mount winch when a trailer is hooked up.
That's why my trailer has a reciever hitch built into it just in front of the bed. Trailer connected to truck, winch mounted on trailer. Dad has used it with his trailer that doesn't have a receiver. He used onedouble hitch recievers between the ball and the truck with the winch poulling from there. It was just loading a dead first gen Ranger, but did fine.
Nice thing about reciever mounted is mobility and versatility. Remove when not needed, plug into vehicle reciever if necessary. Push come to shove, chain the winch around a solid object and pull away. Just be mindful of the strength of the object and the load on the winch.
I bought another Badlands winch during holiday the sales. Got a 3500lb to mount on my Honda Rancher. Will probably never see much load, but I wanted one to drag deer out of wet swampy areas that I wouldn't drive into. Didn't like how the smaller ones were built without tiebars. It'll never be taxed with a deer, but I can't day I'll never overload it and I've seen the smaller ones break from the drum support bending/spreading apart under load.
