Hi,

I have been reading through various forums and trying to get some advice on the Superglide setup with my 2017 3500 4x4 megacab 6'4" bed (without factory fifth wheel prep and without factory air bags). Because of the standard bed I think I am leaning toward an Autoslide.

The trailer I will be towing is a newer fifth wheel but it has a light hitch weight of about 1,330 lbs. I am concerned with the light hitch weight that the trailer will be nose high.

I will be towing full time so I am not concerned with having a "clean bed" The hitch will stay in the truck bed full time so also OK with standard rails.

Do you think standard rail mounting system with the Pullrite Superglide model number 2700 or 4100 (both 16k hitches) will work? I guess I will need whatever setup that will have the lowest hitch height?

Thank you.

Nose high has noting to do with hitch weight per se....it is about getting trailer level when hitched to truck

That all depends on truck height/trailer height/type of pin box and adjustments that can be made to hitch/pin box/trailer suspension

Either by raising hitch in bed of truck, lowering pin box in trailer or doing 'mods' to trailer suspension to raise trailer height.




That 1,330# hitch weight (pin weight) sounds like the mfgs published "DRY" pin weight based on DRY trailer weight (Unladen vehicle weight---UVW)

What is 5th wheel that you are purchasing/have purchased?
Typically 20%-25% of trailer actual camp ready weight is what WET pin weight will be.


Is it time for your medication or mine?

Hi, thanks for the reply. I was mentioning the hitch weight because it is fairly light and wont bring much "squat" to the truck to help bring the nose down. I have read the problem with the Superglide is there is no hitch adjustments for raising or lowering...

I forgot to state the 5th Wheel...I am looking at the CruiserAire 25rl. Yes that 1,330 hitch weight was just published weight...

No matter what the squat is you need to go by the bed rail clearance. I'm runing an 18K superglide with a 3500 Ram. The squat will figure into how level it rides but again bed rail to FW clearance is set first then level the rig which can be a matter of moving the shackle a hole or so, adding a correct track? for a couple inches, flipping axles or going all the way to an additional sub frame.

I just measured mine. My hitch plate is about 1 3/4 to 2 inches below my bed rail BUT I also have the optional low profile feet. The feet go between the picture frame and the hitch. The low profile feet drop the overall hitch height by an 1 1/2.

From the face of my pin box plate to the underside of my FW it's 11 inches. 11 minus the 2 inches my hitch plate sits below my bed rail gives me about 9 inches of bed clearance to underside of FW give or take. I thought I had measured about 8.5 at one time but it depends on how it's sitting when hitched. i may be a little on the high side of rail clearances but I do a fair amount of off road maneuvering and have backed into a few wild looking areas so I like clearance.

I had the standard feet when I bought the hitch. I installed everything and then dug the FW up onto wood blocks until level. At that point I first knew that I had too much rail clearance. When I figured that I woukd drop an 1 1/2 with the optional $80 feet I then subtracted an 1 1/2 from the blocks of wood that were under the tires and determined the amount of lift needed to level up. The first thing I did was go to 16 inch LT tires and new wheels. I then flipped the axles, added a Dexter ezflex and wet bolts.

My bed didn't have the factory pucks so I bought the Chrysler kit and installed it myself. Also bought the picture frame from them. How wide is your FW and are the front corners rounded or cut in? I needed all this because of short bed, flat front FW and 101 inches wide.

Only low profile feet

Edit: Also, my pin box is moved all the way up.

Hi azrving,

I was wondering what hitch you have what year Ram you have. Do you happen to know the height of the hitch?

I received some information from Pullrite. It appears to get the lowest hitch height setup using a Superglide hitch, I would need to use the standard rail mounting setup, not using the OEM Ram 5th Wheel prep kit (which I dont have in my truck anyways). The reason why, Pullrite does not make a hitch that plugs directly into the OEM 5th wheel pucks. You need a picture frame adapter and in certain situations you need an additional adapter to use the OEM puck system. So using those adapters can raise the hitch 3" to 6". If using just the standard rail mount, this is about a 1" rise.

From Pullrite, the 16K hitch model 2700 is 17.25" tall. Using the standard rail mount that adds about 1" more...that would be about 18.25" tall

The 16K hitch model 4100 is 14.5" tall. I'm no too sure of the mounting system for the 4100 model hitch so not sure how much additional height that would add?

I was curious if anyone that has a late model 4x4 Ram uses a hitch that is about 17 to 18" tall? If so did you have to do any modifications to the trailer (lift etc..) to get the trailer level?

Another note, I do plan on changing the stock wheels/tires to 16" wheels and LT tires..
