Height of 5th Wheel Hitch

[CanDo]

I have read with interest much of the discussion on this forum about air hitches and air pin boxes. As we are going to begin fulltiming later this year I am leaning toward an air hitch for the most comfortable ride and to minimize stress on the TV and Monty.

I went to the trailer saver website and noticed that it stated that the basic hitch (TS3) is 14 inches high with 2-inch and 3-inch "lift kits" available if a greater height was required. It never occured to me that the height of the hitch was an issue - the dealer from whom we purchased our Monty installed the hitch in our original TV, a SRW Dodge 3500. We have since traded that truck for a dually and had Camping World install a new set of rails in the new truck on which we mounted our original Reese 16K hitch. We have not towed the Monty with this new TV yet so we don't know if this will be a problem or not.

Being the curious type, I measured the height of my hitch from the bed of the TV to the top of the hitch: 15.5 inches. Assuming (and you know what that does!)that the beds in the dually and the SRW trucks are the same height from the ground, I would need to buy the 2-inch lift kit with the hitch.

Here is the question (I know, FINALLY!): Can anyone tell me where I can find out just how high the hitch has to be off the ground? Am I making this too hard? Since we are going to be fulltiming, it is important to have the Monty level when towing, right? How do I make sure that happens?

Any assistance with this problem would be greatly appreciated!
