Guys, I wanted to pass along the following information. I was at the Mopar Nationals and helping Geoff work his vendor booth since he's giving the club a $450 gift for our national meet. One of his displays was this cool aluminum adjustable hitch with a built in scale to show you tongue weight. Also, the hitch includes both a 2" and a 2 5/16" ball. The stainless steel balls are held in by a pin and can be quickly changed without tools.
Here's a website of the hitches, but with a mini-group buy Geoff can beat these prices. I believe he said that as a distributor for these hitches, he gets a price break for every 4 that he orders, so it won't take much to get a decent discount. (I'll confirm what his price break will be once he sends me an email, forgot to take note of his show special sheet at the nationals.
