So Jeff there you have it...There are a lot of hitches out there (Reese, Curt, B&W, Demco, Pullrite) doing what they were purchased to do which is to hook up and pull that 5er down the road to the next destination.
I agree with that if you don't need a slider go for the 18K, if you do need a slider then go for an auto slider....
Bottom line up front...all of them will get you down the happy RV trail safe and sound as long as it is installed correctly and the weight rating is correct...
Enjoy and happy trails...
