New HD truck bed rails too tall for 5th wheel

Options: tow with the trailer nose high, or spend the money to lower the truck (easy on a Ford, tough on a RAM and with resulting possible drive train/warranty issues), or raise the trailer (with resulting possible height/suspension issues).

How are people getting enough bed-rail-to-overhang-clearance without having the fifth wheel be too nose high?

Want to hear from people who have done one of those three things and how it worked out for them. Also welcome ideas and suppositions and recommendations and thoughts:)

Trailer (Cougar 23mls) is already very high on flipped axles with frame to ground at 23-24 inches. I would hesitate to raise the trailer more, not to mention the cost., but could be done.

Am getting a 5th gen Ram 2500 Hemi 4x4 CC. RAM’s have coil springs in back. Lowering kits are sold, but not recommended? What to do?

The solution for my current rig was to replace the F-250’s OEM 2.25/2.50 inch rear leaf spring spacers with 1 inch spacers (after assurance from two Ford Service Managers that it was okay). That resulted in about 5 inches clearance with trailer slightly nose high and truck squatted slightly - livable. (No issues with drive train or suspension on truck).

  • That little trailer won’t sink a Ram2500 “that” much. I’d expect 2-3” drop. Since they have a fairly compliant initial spring rate.
    Or if you’re getting an air ride model, alt trailer height gains you an inch in clearance. Although you could crank down the height a little on an air ride by adjusting the sensor rods. Not too much, don’t want to run out of susp travel, but your load is light unless you’re carrying a bunch of extra weight.
    If I “had” to lower the rear I’d want a leaf spring suspension to play with if you’re reverse leveling.
  • Not really a 5th gen, 4.5 is what the newest are called as they are NOT totally new.

    How do you know the RAM won't settle in at the correct height??? Unloaded bed height has nothing to do with loaded bed height.
  • I have not raised my FW, but tow about 1 1/2"s nose high. I have my hitch set to allow about 6 1/2"s of bed clearance. Works great for me, no issues. I'm sure you've noticed many FWs being towed very nose high, too much IMO, but they are doing it.

    The Correct track alignment system, has been used by many, to help raise the trailer with similar issue to yours. It will raise your trailer, just over 2"s, and allow for alignment, likely better than OEM. It is not expensive...can be seen/reviewed at E-trailer.

    I'm curious why you are going from the 21 Ford with 7.3, to the Ram with Hemi?
