Pinbox hitting bedrails

[2 DA WDS]

Hello all, I have a 2015 39DBRS3 with a Mor-Ryde pinbox. When I make a sharp turn the pinbox hits the tonneau cover rail attached to the inside of the bedrail. I have been lucky so far to stop when I hear it hit to not damage the bedrail. I have the truck hitch raised to its highest position but to get the rear part of the hitch to clear the bedrail it would have to be higher than the bedrail.
I have talked to MorRyde, Lippert and DRV and none of them have a solution. Is anyone else having this problem? Or a fix? In this picture you can see the metal sticking down at the rear that is almost level with the plate that rests on the 5th wheel hitch.

I have the same hitch pin as you and went out to look at it closely. To me the metal that is below the mounting bolts does not appear to have a purpose. If it was my trailer I would cut those two pieces off.

When I towed my MS, before I had a hauler body put on, the underside of the trailer was much too close to the rails. I use a Trailer Saver hitch which appears to be a bit lower than other hitches but I like to have at least 8 inches over the rails.

Same exact problem a friend had on his Chevy towing a different brand of trailer. After looking at the situation, and with his blessing, we cut those ears off and corrected the problem. Used some black paint to cover the edges we cut and he was a 'happy camper'.

Lippert says that if I cut those off it voids the frame warranty.

I'm a realist, what difference does it make? I guess tearing up my box rails is
something I would not live with. I'd cut the ears off to fix the problem. They would have a real struggle explaining to me and anyone else how that would cause the rest of the frame to fail.

[billr]

Cut off. That's what I'd do Tom. Lippert are being stupid.

Tom, I had that problem as well and I trimmed off the cover rails where the hitch hit. Had to trim about 1/2" at the widest point. I used a sawsall. I measured where the hitch started hitting and then trimmed kind of a half circle. Call me if you want to discuss.

Lower the kingpin, then lower your hitch

[2 DA WDS]

Kerry, the pinbox has a sticker on it saying 24,000 lbs with 6 bolts and 21,000 with 5 bolts. It has 6 in it now and if I lowered it it would have 5. I weighed the trailer at 20,200 so it should be good to try lowering the pinbox 1 hole. Then see if it clears and if it is anywhere near level since I have the 2" riser on the frame.

Tom,
Lots of years difference, same problem, MorRyde extended pin. I cut the metal angle that everyone above has said to to. Did it with a sawzall, painted the bare metal and have not had any frame problems. But my '05 is only 17400lbs and uses only 4 bolts for the pinbox.

I have a 2015 MS Dallas with 2" llift. The truck is a 2014 Ram 3500 4X4 dually with TrailerSaver hitch. Everything works well ( except the 5W, a lot of problems).

Assuming you have an adjustable RV suspension I would suggest you lower the pin box and raise the RV to level it out. This would give you more bed rail clearance.

[2 DA WDS]

No adjustable suspension, Mor/Ryde IS. If it ever stops raining and I can move without getting stuck I'll start measuring and adjusting. They brought in rock today to try and cover the mud but the rock truck got stuck. Need to get out of here and head to a dry spot, maybe California!

[golf_bears]

How much interference are we talking about?

Interference?

[golf_bears]

Interference, by how much does the pin box hit the bed cover rails, 1/8", 1/4", 1/2" 3/4", 1", etc?

[Stripit]

When I helped trim the box for my friend we cut almost 1 inch off the ends, on an angle that left him enough clearance. You don't need to cut he whole box to get the box to clean the bed rail. Never touched the bolts or for that matter came close to them.

[2 DA WDS]

It didnt rain yesterday so I did some measuring and inspecting. Turns out the very low part of the box at the front is not what is hitting the tonneau rail it is the rear part of it which should be high enough to clear it. So next time I hook up to move I'm going to have to do some more measuring and inspecting.

Are any of you that have a contact issue using a TS-3?

[HOWITTRO]

Kerry
Was it your idea to add the 2 inch riser to the frame or your dealer. I spoke with Kyle at DRV and he said they rarely add this feature yet Karen at RV's for Less who is the no 1 DRV dealer in terms of volume says she always specs this feature on all her builds. The concept makes sense to me to provide more clearance to the bedrails
Bob

Added 2" Riser to frame

[Kerry]

Bob, I have the Trailer Saver hitch. After reading on the Suites forum, which is still not working, and other forums, and also on the recommendation from Ken at Rvs4less, I opt for the 2" lift. The guys at the factory don't tow or camp, enough said. I also have, but not using, the 2" and 3" TS lift kits. I got them just in case I needed them when I picked up the MS. If anyone needs either, I'll sell each lift for $75 each. ($150 from TS). Anyway, my Dallas tows level.

No different with the group that is now the managing end of MS.

[suiteowner1]

My Mobile Suite is equipped with the Trailair air ride model #1621 with low air pressure in the airbag it will hit the bedrails...But with the proper air pressure 80 psi. I can jack the MS 90 degrees with no trouble at all...If I had this clearance problem you folks are experiencing I would be so annoyed with DRV for installing something like that on my RV...

[suiteowner1]

This pinbox will solve all your clearance problems and rides wonderfully..

I agree! I had one on my 07.5 MS and added the TriGlide. The new 16 MS has the same thing and it just floats back there!

[2 DA WDS]

I'll be at the factory at the end of this month for several repairs and see what they have to say.

Are any of you that have a contact issue using a TS-3?

Glad I found this thread, as I'm having the same exact problem. I am having to replace the mounting rails for my tonneau cover this week, and I may have tweaked the truck bed rail slightly (but no cosmetic damage.).

I have the TS3, and I automatically assumed those "wings" hanging down from the frame behind the pinbox bolt was the issue. But if you measure those, they cannot reach the bed rails even at 90 degrees of jackknife. The contact appears to be the aft-most portion of the frame, up where they mount the breakaway brake box.

I also called MorRyde and DRV and they were both scratching their heads. Only thing Rob said for sure is that he wouldn't recommend lowering the pinbbox by going from 6 to 5 bolts. But it sounds like I'm not the only one out there with this problem.

I definitely don't have enough clearance between the bed rails and the underside of the trailer. And at the rear, near the tailgate I have even less clearance. The trailer is riding a bit nose high, and this decreases the gap. I have the 2" riser under the TS3 hitch and don't want to decrease the clearance up front any more by removing it. So, the solution appears to be raising the rear of the trailer 2" (MorRyde IS back there.)

Until then, I have to be very careful not to rest the trailer on the tailgate by going into twisting up or down driveways. I won't be able to get to the MorRyde factory until April......so fingers crossed between now and then.

HR, for additional bed clearance you could lower the rear of the truck. It was the best solution I could come up with and it works out well.

[2 DA WDS]

The factory fixed mine. They lowered the pin box and were able to still have 6 bolts in it. I saw some 43 footers there that only had 5 and no weight rating on them. Mine was the only one I saw with 24000 6 bolts and 22000 5 bolts sticker on the box.

[HighwayRanger]

I looked today, and saw no such stickers on my pin box or frame area near the pin box.

Leo, how did you lower the rear of the truck? Something about shackles?

Hmmmm............one of those 43 footers may have been mine. We go to Rolling Retreats Tuesday to see our new rig for the first time in person. I will be checking out the Mor Ryde hitch status for sure.
