We bit the bullet and did a Moryde pin box as well as a Trailer Saver hitch; tried it out last month on a 5,000 mile, 18 day trip and it was worth it! The 'hammer' at the rear axle that used to happen at uneven railroad tracks (and similar places) is all but gone, as well as the chucking at stops/starts/etc. The Moryde and Trailer Saver replaced the stock pin box and a Curt 26; no complaints for either one - but the difference is amazing. The ride was much better on me and spouse, and I have to believe the life of the TV (2012 Ram 3500 DRW - Cummins) and the 2013 Cyclone 4100 King have been extended.
