Started out with a manual slider that dealer through in the deal when purchasing 5th wheel to tow with Ram 2500 SB. Didn't like the hassle of manual moving the hitch. Found a deal for 1/2 price on Airborne Sidewinder. Biggest mistake I made. The wedge would not hold tight and would pound out from being too thin in material thickness.. I made my own wedge out of much thicker material and used larger bolts to hold in place after adjusting the wedge tightness. Still towing it was like the tail wagging the dog with the pivot moved back 20 inches, especially in the tight curves through the mountains..
Finally went to a 15k Pullrite auto slider and it is the best move I did.
My trailer is a Jazz 3300, 36" long, triple slide, 12,000+/- lbs. depending on how loaded.
