Drop in Bed liner with RamBox? with Fifth wheel holes?

[Bluegill1]

OK, I picked up a 2014 2500 Tradesman with RamBoxes. I'd like to either do a spray in liner or preferably a drop in bedliner, previous owner had a fifth wheel, the mounting holes and outline kinda make it obvious.
My question is,

1. If I do the drop in, I assume it'll be the "under bed rail" version?
Also, I assume the RamBox rail system has to be removed to get the drop in behind the rail system?
Drop in the liner then re-install the rail system.

I'd also like to get some snap-in caps to fill the Fifth wheel mounting holes, four of the holes are pretty big, the others are probably small enough to be left alone.

Reason for the dropin -vs- the spray in is only because of cost, dropp-in is like $330. I'm assuming spray-on will be in the 6-700 range.

Anything I'm missing? anything I need to know?

Thank you,
David

Linex is usually 450 to 500.. get linex and find caps for the holes... or patch them up now before linex and holes will disappear...

Make sure your dealer is part of the lifetime warranty...
