question about king pins

ok so today was supposed to be new trailer day but even with the sliding hitch the 5th got too close for comfort to the back of my cab so i have ordered a king pin extension that gives me an extra 10in which should be good but the thing im concerned about now is when i turn will the pin box come in contact with the bed sides, the reason i ask is because my other option is a reese sidewinder but that is more then double the price and seeing is this is out of my pocket now i would prefer to try and keep as much of my money as possible

anyways here are a few pics with it hooked up




i know the ass looks low but it is partially where i am parked and partially the levelling kit, when i get some extra cash im going to add another leaf or buy a new truck depends on when i get a job

I think your unit is too close to the rails (at least the picture appears that way). If you go over any uneven roads you could slam your rails into the lower portion of the 5th wheel. Not to mention possibly punch a hole with one of your bed corners. There should be a minimum 6 inches clearance all around. You look level now so you might need to raise your axles on the 5th.

The extension you have above should raise your height if you leave the hitch height as is. If you lower the bolts you could still have the rail issues.

Hitting the side of the truck depends on the king pin length and you should measure it before making a hard turn.

actually i have been doing alot of reading, i think i am just going to bite the bullet and get the sidewinder, it give me a worry free tow experience where i will always be worrying about the extension, and i can adjust the bolts on the pin box to level out the trailer with less issues

The pictures look to me, as well, that there is not enough clearance between the underside of the trailer and the side rails of your truck. Six inches is the minimum; that's about what I have and that is just barely enough in some situations and really not enough in others. Most hitches are adjustable up and down so that this distance can be acheived

I also have a short bed on my Ram mega cab (6ft)

The pull rite super glide, centered over the axel, appears to leave a lot more room between 5th wheel and cab.

Also agree with observation about clearance over bed rails.

I also have air bags that help keep the truck level with tongue weight of the 30.5

I guess I just have to agree with most others on here. I have a Ram 2599 Cummings and a Pull-
Right slider with a Trail Air super glide, and have "dented" this truck and an F-350 Ford as well. It is going to depend on how up level the road you are traveling on is, but it sure looks like too little clearance between truck sides and trailed bottom in hitch area. I adjusted my the pinbox 3 times, and have now got it pretty good for now.
It certainly depends on how level the road you are on is, but I would not be comfortable having that small amount of clearance..
You may have to adjust both the pinbox and the trailer axles I would guess?
Just my 2 sense..

Between the mounting rails and the hitch, the total height profile of my super glide is 22 inches, and sits level with the bed of the truck

The additional clearance that you see in my photo comes from the pin profile itself.

How does you hitch compare?

--- I think referring to how to increase the distance between the bed rails and the underside of the trailer.

Most pins are adjustable in terms of how low the pin box hangs from the trailer by having multiple adjustment holes in the box. The lower the king pin box hangs, the more distance between the rails and the trailer. This makes your trailer ride higher, which can make it un-level when towing which is not good, either. This can maybe be handled by changing how the trailer axles are attached - not as big a deal as it sounds.

Where is your dealer on this? He should offer to help you get this kind of thing set up.

How much clearance do you have as is now?
