5th Wheel/Camper Shell Toolbox

[PredatoryKey]

Hey everyone!
I just bought a 2020 2500 Laramie Longhorn. 6’4” bed and crew cab.
Only thing I miss about my Ford is the under seat storage.

To fix that, I was going to get a locking and waterproof tool box for the bed that goes against the bulkhead.

However, I want to make sure it won’t interfere with my Leer camper shell I ordered or my 5th wheel.

I’ve never purchased one of these before and can’t seem to find good options of what’s good vs. what’s not online.
Anyone have thoughts on this? Suggestions? Want to get something ASAP.

Thanks! She’s been my dream for years. Couldn’t be happier. Just put new Cooper Discoverer AT3 XLTs on her as well. Upsized to 295/70/18 from the stock 275/70/18. Way better tires. Way better look.

I really like the way the HPI fifth wheel toolbox looks and the weather guard of course. But I’ve not had either product in a fifth wheel box. Are there solutions that you don’t have to drill through your bed to mount it?
