Winch attached to R1T trailer hitch

This would likely work if you want a lithium battery.

Dakota is excellent. In my experience, you pay a lot and it works forever. But other less expensive ones have been just as good to me.

There are, I shit you not, at least 15 LiFePO4 and 30+ LiPo/Li-Ion batteries in my house/RV/car/motorcycle right now. I am probably under-estimating. I've got at least half a dozen various charge controllers and systems for all of them.

I just realized that I have one, single AGM/lead-acid still in my life, in the Smart car. I've run the battery restorer on it twice, and it comes back. I like to push shit to the limits and see what happens. When it's done, that's it, never again will I see lead-acid. Like carburetors, they are dead technology that I never want to deal with again.

It would generally be nice to have a high amperage 12V connection. I wonder if maybe it might be possible to hook into the wiring that feeds the inverter under the driver's seat? It has a direct connection to the HV with a step down right? What is the fuse on it?

LOL, you want to deal with 400v+??

Yeah, that's the thing about messing with an EV, freaks me out.

Would definitely be nice if they would provide some type of high current 12V access.

They do seem to, I covered it earlier in the thread.

One thing I've been thinking of is since the winch needs to be mounted on the rear it will not be conducive to pulling the Riv UP a hill. Was thinking with the "portable" battery could attach the winch to a tree or something but there will a lot of transverse torques, making me think the whole winch and plate will want to spin if it's not rigidly attached to something.

Really need a front attach point for this thing! Something that clamps onto the front tow hooks? Anyone know how the tow hooks are attached?

Yes, the 300A terminals? My concern would be if the winch tries to draw more what happens? I guess you could put a 250A breaker on the winch. You wouldn't get the full power of the winch.

Depends on the winch size. I've measured a few, they pull less than everyone assumes they do. On my Jeep the 12.5k winch ran a 300a fuse.

Should it matter? Since you never really know what orientation you’ll need help from. The two times I was pulled out by someone else was a rear recovery. Plus I love the idea of easily removing it after each recovery/trip.

I've never had a use for a rear winch, and dozens for a front winch.

The advantage of the hitch mount with the 12V battery is you could attach it to another vehicle with a trailer hitch.

I guess I'm hoping there is a step down transformer before the inverter so it is a more reasonable voltage but still high amperage for long duration.

I did also see your comment about 300a terminals. I must have missed that the last time I opened up that tray. I'll have to look. It would be nice to confirm that is true. As you said you could put a fuse in front of anything attached to it.
