We don't have a Columbus, we have a 2012 Palomino Sabre 32RCTS. We use a Pullrite 16K slider hitch and just installed a Trailair Tri Glide pin box. Although we've only taken one short trip since installing the new pin box, we noticed a big difference in the way the trailer pulls. Worth the investment in our opinion. We feel it is a very good combination but these two devices perform different functions so using them together doesn't make either of them perform better than they do on their own.
First and foremost, you'll need to know which pin box you currently have to make sure your ordering the correct Tri Glide pin box. Our original pin box was a Lippert 1621. Chances are very good that your pin box is the same but you will need to verify that. The replacement for the Lippert 1621 pin box is the Tri Glide L05.
Sammy, the capture plate you are speaking of doesn't have grease fittings. The Trailair pin box does not have grease fittings on the lower jaw, the Trailair Tri Glide pin box has grease fitting on the lower jaw. Don't be confused, these are two different pin boxes. There are two different capture plates that can be used. One for a pin box with grease fittings, one for a pin box without. If you are ordering the Tri Glide pin box, you will need the capture plate that works with the grease fittings. Here's a link to a fitting chart to determine which Tri Glide pin box you will need. Again, you have to determine which pin box you have now before you can move forward.
