Hey Jack,
Good looking rig, I admire you people who actually get things finished, as opposed to me, who usually gets it usable. I am making an effort on the bus to correct this flaw.
I did a little velcro zipped cover to slow down the rust.
I didn't think you had enough humidity out there for that to happen.
The tow bar is a Roadmaster Stowmaster. Rated at 6000lb. It probably is a finger pincher, I'll probably find out one of these days. I'm more concerned about the Jeep frame where everything bolts up than I am about my welds and brackets. Boy, that stuff is thin.

I did use grade 8 bolts and large backing plates with proper torque, hoping to maximize the clamping forces and area that is being pulled on.
The PO said he was selling the hitch because he couldn't back up with it
Somebody probably told him he could do that with no problem. That bend looks pretty insignificant.
The Jeep tows 4 down, you just have to make sure you get one with Selec-Trac. It allows you to put the transfer case in neutral.
Next is to see if my idea for putting the receiver in the rear bumper works out. But, that will have to wait for a bit, I've got to make things a little more livable inside. Mumsywumsy is going on a trip with me next week. It seems that what she will put up with and what I will put up with are a bit different.
