I think older fifth wheels have lower pins. newer trucks have higher bed rails. my fiver is 2008. my hitch is at its lowest setting. bed rail clearance is fine. even lowering the back of the truck a small amount will make a difference.
can you raise the pin box on the 5er? i had to raise my pin box and lower the hitch
raised the pin box 2 inchs
It’s as high as it will go.
Is the trailer setup with the axles under or over the springs?
I totally understand. the alt ht is 1-11/2 lower than standard ht when loaded. I would think if ram thought it was ok they would have had lower settings. That being said its going to be trial and air. AS i said before i would raise trailer. that is what i have done in the past its alot of work but the best and safeist way.
I have shortened the rods an inch. Has not affected the ride unloaded. Will know more when I hitch the fifth wheel. 5200 lb pin weight.
sounds good. could you let me know how it rides when loaded and fender opening ht loaded
The way it is constructed, it looks like a 1 inch shortening of the rod will result in 1 inch lower ride height than stock at both normal and Alternated Trailer Height. If I don't generate any error codes, I will be happy. I don't think I will see any codes as I am pretty sure ride height info comes from the sensor at the end of the rod. Will know when I get my arm out of a cast and hitch it to the trailer.
sorry to hear about your arm. Let me know how it goes when you can try it with rv hooked up
Got my fifth wheel hooked up with 5K pin load. No error messages. Using alternate trailer height. Links are 1 inch shorter than stock. Appears to lower wheel opening an inch. Will be on the road tomorrow but don’t anticipate any issues.
thanks for the info. let me know if it rides any differently than before
Got back from 400 mile trip. Rode fine. Down an inch compared to before installing the links. Still getting “ride height sensors circuit signal amplitude below minimum “ error on both side when I scan for codes. These don’t show on the cluster. About half way through the trip I got a “Service air suspension system” indication on the cluster and a ”Left Mechanical linkage failure“ code. Disappeared when I dropped the trailer at 200 miles and it never reappeared. Link was fine. I will try adjusting the link to 3/4 inch instead of 1 inch and see if that doesn’t get rid if the messages. Regardless the lower ride height worked.
thanks for the info. will keep info for future info. may do this mod. what are you using to ck and erase codes with
Blue Driver
