Lots of good info from folks, thnx!
Yeah, I think a WD hitch is a good idea for a 1/2 ton.
Don't know if I'm getting something, but thinking about it. My V10 truck is getting old and I don't really need that much truck for towing my new Jeep, which is going to be lighter than a stock TJ. Loaded trailer ought to be about 4800 lbs or so.
