Those that have used Anderson Ultimate Hitch

The Curt hitches start at 13". They are the only one's I found that have that start with that low of an adjustment. The others I've looked at are 15 1/2 and up at the lowest adjustment point. Without knowing how much the rear of the truck will drop after the pinbox is dropped on the hitch, it makes it darn difficult to know what to do. Measuring my 2016 Ram 3500 and having the fifth wheel level, it looks like I have 13 1/2 - 13 3/4 from the bottom of the bed to the top of kingpin. It's a heck of a thing to drop $700 + to find out the hitch you bought will not tow the RV level or provide the bed rail clearance needed.
