towing V20 w/explorer

This is right at the top of my boat to do list.

I tow with a 2001 Explorer, and I need to get a real hitch like I have on my old van.

I haven't weighed my rig, but with the trailer it is probably around 4800 on a 5400 GVWR trailer.

I got the last hitch installed at u-haul down in florida, but that was almost 20 years ago.

Any suggestions?
