Which hitch?

[GraftonGuns]

So, I am towing nose high about 3-4" I Can see the temperature difference between the rear tires and front tires of my 27.5 RLTS ..I've looked at putting 3" spacer blocks between the axles and leaf springs and am not really in favor of that as it will raise the height of the trailer. My current hitch is a Curt A16 (came with the trailer) and cannot be lowered. I am thinking about getting a different Hitch for my F-350 short box. And, No I do not want a goose neck setup. Any Feedback would be appreciated..

How much bed clearance do you have? Can you adjust the pin box? A new hitch may not help.

Is the pin box on your fifth wheel not adjustable, or do you already have that on the lowest setting?
