Proper kingpin height for hitching

it's easy keep thing just snug back under with trailer level pin plate should hit the back incline and shove the truck down.so back up until the front of the kingpin hits the back portion of the plate at level.

once tightened up and hooked on you should have 6" s of clearance to the bedrails

All the tricks are just overthinking it, in my opinion. Just to avoid getting out of the truck?

In most cases you just need to remember where it was when you unhitched, and go back there. You can get levels that will remember for you. I don't bother with all that stuff. Just back up until the pin and the hitch are close. Get out and look, and if I miss remembered where I unhooked, make a small adjustment.

All the tricks to avoid getting out and looking, are just asking for trouble with high hitching. Can't go wrong if you GOAL.

You don't need to have the pin level with the hitch to connect, in fact trying to do that can lead to "High Hitching"! You want the pin plate about 1"'lower than the hitch plate, even up to 2" works just fine! You really want the pin plate ride up the hitch plate a bit the will prevent high hitching.

This idea works for others:

Acquire a 70" piece of heavy string, and a bolt or washer for weight, and a bread wrapper wire tie.

Tie bolt or washer to one end of string.

After unhooking from your RV and BEFORE making any leveling adjustments to RV, place bolt/washer on ground under RV hitch pin.

Lift other end of string up to the bottom of hitch pin being careful NOT to lift bolt/washer off the ground.

While keeping string taunt, wrap wire tie on to the string at the bottom edge of RV hitch pin. This is the exact height your hitch pin needs to be at prior to hooking up your tow vehicle (TV).

Go camping and have fun.

Prior to backing TV under hitch pin, use string, bolt/washer and wire tie to reposition the RV to the exact height as when you unhooked from TV.

A simple and very inexpensive aid to assist you with proper hitch pin height for hooking your TV to your RV.

Hope this helps?

Add a short length of small chain to the end of the break away cable so it just clears the ground at the disconnect hitch height.

Quick and easy. Works like a charm.

You could measure the height of fifth wheel plate in truck bed from ground and then raise trailer kingpin plate to that height to get closer then backup close, get out and fine tune height. My level up system will remember the last unhitching height but I still get out to make sure!
