I wish I could afford that GV rear bob.
I'm running on 4.10:1. Talk about reaching for a 6th gear on the highway.
I have a taller set of tires I put on to get the rpms down. They help but I got lazy once and left them on while towing. Lets just say the hills weren't much fun and I was glad I had the granny gear.

On the twitchy part, try a stiffer steering dampner. (The shock bolted to your steering arm) The ones for big mud tires are stiffer. It will make for nicer towing as well, less arm fatigue.
