I only know of one person that has the SwingCases..."Coskid" down in the 2004-2008 F150 forum. He has a soft rollup from Extang and there are no clearance issues. I don't know why it wouldn't work with the Trifecta...maybe an issue with clearance for the latches on the cover? Sounds like you might want to call Undercover about that.
That sucks, I just bought the cover this summer. I guess I'll have to look for other options for a tool box for the back of the truck. Thanks for all the information.

They have under the rail tool boxes which are generally available in any auto parts store. I have one with the Extang Tri-Fold. The only problem I have with it is that I have to loosen the Tonneau and slide it forward to get at it.
