Riding nose high

[Mwebb61]

Hi Everyone !

This is my first time posting onto this forum. ME and my wife recently got into the 5th wheel scene moving from a 26 ft TT and are loving it so far. I had put in a Pullrite super glide on IS rails that are under-mounted so the hitch can be completely removed and have the truck bed flat. Issue is, with the IS rails the hitch sits high in the truck bed. I already adjusted the pinbox up to the highest bolts and when I add air to airbags its got about... 9-10 " of clearance from bedrails. From the jacks to the ground the front is 14" off ground and read is 6" off ground.

I was given the option of adding blocks ( which will keep clearance in bed) or to change pinbox. I was wondering if the MorRYDE pinbox replacing the road armor pin sits more flush vs angles and will lower the nose for me. The axle appears to already be "flipped" with leaf springs above per other advice I've read.

Welcome. Just a quick bit of info, 9-10 inches is a lot of clearance to your bedrails. Most of the time the recommendation is 6 inches. Mine is at 5 and 1/2 and I have no trouble. Good luck and enjoy your rig!

Welcome. 7" is recommend.

[Mwebb61]

I was hoping to lower the clearance to 5-7 inches by changing the kingpin …. Does anyone know if that would work switching from stock to morRYDE ?

Can you lower you 5th wheel about 3 holes?

[Carl n Susan]

The pin box is as high as you can get and you are still way nose high (14" at the jacks and 9" at the rear). I suspect you have 16+" of clearance from the rails at the hitch. I doubt the Mor-Ryde will be much different from the existing Road Armor.

Too many hear have the Pull-Rite hitch with normal 6" rail clearance so it seems the IS function is more of the problem? I don't have nor know squat about the Pull-Rite. My friend has one in his Dodge and he has the normal clearance. Of course he rarely removes the hitch as it is a beast.

That's the only problem with the Superglide. I don't think it is height adjustable. Some sliders such as the B&W Companion and Curt Q do have height adjustment.

I have a Superglide with a MorRyde pin box. I think I have 6-7 inch bed clearance but do run maybe an inch or two nose high. I guess maybe each truck sits a little different.

Good morning to all. Have you measured the overall height of your unit (to the top of the front a/c unit?) I am curious about the bridge clearance in the current configuration. The ride profile can be adjusted several different ways to get the unit level and riding correctly and have an acceptable bed clearance. Just make sure in the end, you still have an overall height that provides the bridge clearance that you need.

Nose high is one thing but that also generates TAIL LOW condition which could generate bigger issues. King pin looks like it could go up several holes. Trail shop did a little trim and moved mine up.

[Mwebb61]

So originally it has 3 holes where the pinbox connects to the trailer. I moved it up higher because the original bed clearance was like nearly 12". now its about 9". Still too tall. So it seems like my only options are to change the IS rails the pullrite sits on to the lower profile non removable style, or add leveling blocks to the back.

The reason I was asking about the switching the pinbox was because it appeared at first it was slimmer profile. It seems my issue is the additional height from this kit the pullrite is sitting on.

can you take a pic of the current pin box mounting?

As I posted earlier, I finally spoke with someone at Pullrite that gave me direction instead of saying "it can't be done". I have a #2700 ISR superglide. This person told me to look at Curt, Reese, and mopar ISR compatible rails that mount using the puck system. I found this one, https://www.etrailer.com/Accessories...ails=.questins, on eTrailer after repeated calls and googling. According to the literature, it has a height of 2" versus the Pullrite rails of 3 1/2" and will work with the #2700 hitch.
In my situation, raising the pin box and using this Reese rail adapter will get me very close to my desired change of 5".

Thank you ! that was what I was trying to find out. if I can use a different rail thats smaller. Il look into that. Do you think I can maybe switch the rails to a slimmer ISR rail like you mentioned and use a diffrent pinbox to get 3" lower ?

I honestly don’t know about changing the pin box because I haven’t studied that part of the total equation. I imagine you’d have to take all the measurements on your rig and start comparing. I have found that eTrailer is a good resource for information. I know you’ll gain something but swapping out the PullRite rail for either the Curt or Reese.
I am going to take a 2’ level that I keep in my pass through and measure from the top of the hitch plate to the bed. Then, I’ll subtract the height of the PullRite rail that attaches to the pucks in the bed. To that number I’ll add the 2” of the other ISR rail (Curt or Reese).
The main thing to remember is the height between the bottom of the nose/overhang and the bed rails…can’t really go much lower than 6”

Hi I have the Superglide Traditional Model#4400, which from bottom to top of hitch plate is 15.5" high. The Pullrite adapter kit that I used was Model#4409. You can see from the pictures that my hitch plate with bungees attached to keep it level, is actually 1" below the tonneau. I tried to find the Curt model # for you on their Website, but couldn't find it. If you need it specifically, I will get that for you from the adapter itself. The picture of the pin box shows that it is in it's highest position. If you need those dimensions, I can get those for you. Now once I completed the hitch end of the truck, my trailer was still 5" low at the trailer rear bumper. I considered building a sub-frame out of 2" hitch stock & adding 2" blocks, but the Lippert Center Point air bag system intrigued me, & my Morryde rubber spring equalizers were worn out so I went that route. The air bag equalizers lifted the trailer 2", I added 1" spacer blocks under the springs, then when hitched I run the truck in the alternate height position, these 3 things brought the trailer closer to level by 4", now I am 1" low, which isn't noticeable.

You weren't looking for this, but this is what I did to level the trailer front to back. There are cheaper ways, but I chose this route, besides the height issue, I have flexibility now to add air to the heavy side [kitchen, furnace, hot water tank, etc.] I run about 10# more air pressure on that side [60#]

See attached here.

So I moved them up to the highest holes and it's still 10" bed clearance and a 4-5" difference in the front and rear.

Im thinking now that the rails the pullrite is sitting on are too tall. These are meant to come completely out and make truck bed flat but idk if there is an alternative solution.

@Mwebb61 I’m having the same problem with my MHC 295 RL and 21 RAM 4x4 2500. The nose sits 5” higher than the manufacturers stated height at 13’9”. I worry about both bridges and dragging the rear leveling jacks. I have about 8 1/2” of bed rail clearance so I can move the pin box up to gain 2 1/2”. After that, I’m out of options as I do not believe my PullRite Superglide hitch is adjustable. My setup is just like yours. If you find a way to drop the hitch, please post to keep us informed.

I don’t have a slider but do use a 2 inch tubular frame to mount my Demco Recon hitch and had similar issues with nose high and 8 inches of clearance to the bed rails. The solution for me was to go max height on the pin box mount and min height of 16 inches on the Demco hitch, leaving a 6 inch rail clearance. I went with the Demco Recon bc it comes apart in 3, 50 lb pcs that I’m able to handle. Trailer measures 13’-9” hitched - F350 drops about 4 inches but rides level.

You may need a different slider and to measure your current slider height to see where it’s at compared to what’s needed/available.

Don’t know if this Demco slider is right for you guys and if it works with your mount but it does have a 16 inch min height and looks like it might be reasonable to remove. The folks at etrailer are pretty good about answering questions.

Look like Demco makes a 16K version too.
