Saddle Truck Box and clearance with a Fifth Wheel

Do saddle truck boxes cause clearance issues when making sharp turns with a fifth wheel trailer?

I have a Dodge Ram 3500 DRW with an 8-foot long bed. I plan to get a Montana fifth wheel trailer and would like to use the Andersen hitch.

I would like to also have a 27" (extra wide) saddle truck box mounted at the typical location at the front of the bed behind the cab. The truck box sits proud above the bed rails by 7-1/2".

Will I run into clearance problems of the fifth wheel nose hitting the truck box with sharp turns with such a setup?

If so, would the standard 21" wide saddle truck box make enough of a difference?

    BTW, as I was looking into tonneau covers (to cover tool chests or tote boxes), I came across the TruXedo brand.

    I'm interested in their TruXedo TruXport tonneau cover. It installs on top of the bed rails and sits up 1.5" above the rail, hopefully that will be OK. The reason I don't like the tonneau that mounts to the inside edges of the bed rails is because you lose about 3" of bed space on either side and it sits 1.0" above the rail only saving half an inch.

    But what I found really interesting is their TruXedo TonneauMate truck box. It mounts to the tonneau rail and the box sits BELOW the bed rails but doesn't reach down to the bed floor so I can shove 8-foot lumber under the box. IOW, it's a lot like a saddle truck box but below the bed rails. I'd say it's the best of both worlds, but it's no Weather Guard truck box and costs a pretty penny.

    Anyway, it's an option.

    Well that is one solution, not sure if that tool box would hold all I carry.


    I have a TruXsport roll up Tonneau cover and love it the 1" is not an issue.

    Why not not get a below rail tool box and problem solved! Then you can also add a tonneau cover. :B


    The main reason for an above rail saddle box over a below rail storage chest for me is:

    By putting in a below rail storage chest, I lose about 2 feet of bed length, ending up with about a 6-foot bed.

    With an above rail saddle box, I can still shove 8-foot sheets of plywood or 8-foot 2x4 sticks under the saddle box.

    But if an above rail saddle box will definitely interfere with the fifth wheel nose, then I'll have to re-think this whole box idea.


    I have a trifold tonneau cover that when folded is approximately 3 inches high. I have 6 1/2 inches clearance between truck rail and fifth wheel. Twice when maneuvering I hit the front cap. Last time I broke it. There is no way 7 inch box will work.

    I take the cover off and store it when towing. This even with a Pull Rite auto slide hitch. None slider would make it even worse.
