Question 5th wheel hight

Can anyone tell me what the clearance should be, between the bed rail and the under side of the 5th camper ? so you won't hit the bed rail and cause damage to it or the camper

6" minimum - another inch or two for insurance if you can get it and still have the 5th wheel towing relatively level.

Conventional wisdom is you need 6" clearance for pavement and 8" or more clearance for off road.

I had about 5" clearance, but I also had dings on the top of the bed on both sides. Didn't hurt the trailer, but definitely bent the top of the bed. Caused by turning while crosssing a ditch or dip.

If you stay on the pavement and don't turn while crossing dips or ditches, then 6" should be good. But lots of streets have a drainage dip between the roadway and the service station or shopping center lot, so turning into one of those places is when I needed more than 5".

If you don't have at least 6" while the trailer is level front to rear, then you must either raise the trailer or lower the truck. I had one trailer that had to be raised by "flipping the axles" so it would ride level behind a 4x2 SuperDuty. You don't literally turn the axles over, but you move the spring perches from under the axle to over the axle. That raised the trailer about 3 to 4 inches. And caused us to have to buy one step more so old folks could climb into the 5er.

If your tow vehicle is a 4x4, you may have 4" blocks in the rear suspension. On a SuperDuty, you can change those blocks for 2" blocks and lower the back of the truck about 2". Experience says you cannot have less than 2' blocks in a SuperDuty 4x4 because of driveline alignment, so you can't lower the truck to make it the same height as a 4x2.
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 3.5L EcoBoost SuperCrew.

We have towed a 5er with a minimum of 5" and no problems. I prefer to keep 6" as the minimum.

The 5er needs to be level as well.

Lots of possibilities/combinations that can cause clearance problems even with the 6" spacing. My 350 and now my 450 have plenty of clearance EXCEPT when turning/backing sharply, worse if uneven surface--the Morryde pin box has a flange on it that will contact my bed cover rails in this situation that I have to carefully monitor. Raising the trailer to its highest level helped. If I did not have the Retrax cover, I don't think the pin box would hit the bed itself.
