Since you have a full length (8-ft) bed you SHOULD have no issues. Like wingnut said, test it at different angles so you know for sure. The design of the 5er front end will most likely be the determining factor as to how close it comes to your truck cab or toolbox. Our truck has an 8-ft bed with a toolbox very similar to yours and towing with my toolbox hasn't been a problem, ever.
On the topic of tonneau covers, I found one that is designed for trucks with toolboxes that looks like a pretty slick unit.
This lets you still access the toolbox, with cover rolled up or laid down. The main thing I'm not keen on, and this pertains to just about all covers I've seen lately, is the frame for the cover extends above the bed rails, reducing the clearance between the 5th wheel and truck bed. Most times it shouldn't be a problem but is something to consider. The nice thing is it looks like it rolls up to a fairly small package so it shouldn't interfere with 5th wheel/gooseneck towing.
