The new 5th wheel is quite a bit heavier than the old tongue pull, so I installed the Timbren rear suspension enhancement. I planned on installing air bags but kept running into fitment issues with my B&W turnover ball. I ran Timbrens on the Wife's old SUV and they always performed very well so I figured I'd give them a shot on the F350.
I removed my friend's B&W Companion hitch that I'd borrowed to pick up the new one, and installed my Andersen Ultimate 5th Wheel Connection 2. Handling them back to back was a real eye-opener on the weight and hassle of the Companion. I've used both in the past, and while the Companion is a good hitch, I preferred the way the Andersen towed so I didn't hesitate to buy one again. At 37 lbs. it's super easy to install/remove.
