Bob & Chris, If you have a 6-1/2 or an 8 ft box there is no real reason to buy a slider unless you are uncomfortable not having that option available to you. The design of the front cap on Heartlands almost eliminates the need for one. Sliding hitches also allow for more "slop" in the hitch which you will feel on fair to bad road surfaces. This is referred to as chucking. The trail air reduces chucking a little but not completely. The Mor-ryde pin box is better for chucking but doesn't do quite as well for the up & down motion. I think there are pros & cons for both. As for brands of hitches. I have a Reese and like it. I think hitches are like all things, the more you spend, the more you get. As always, plan for the future. You may get a bigger trailer some day.
