How to I base this on? The hight of the truck or the trailer I'd be
I'm no tow-ologists or an expert in this in any way, shape, or form, but I
was told you base the mount on what you are towing. You want the
trailer/boat/whatever to be as level as possible. If the truck height is
too low when trailer is attached, you get a "riser" and if it's too high,
you get "reducer" I have 2 mounts for my 99 Dak, when I tow my boat ( 19
foot ), I use a reducer ( 2 inch drop )but when I use my travel trailer, I
use a straight mount.
