Need some advice--I'm looking to buy a toolbox/storage box for behind the 5th wheel hitch (tailgate box). I was initially planning on buying the V style box, as I figured it would have more storage space, but after diligent research I found there's limited options (Better Built at Camping World and Unique Manufacturing out of Sturgis, MI). The flat style "Partner Box" is the other option, but less room for storage. I'm running a long bed and usually only tow the 5th wheel, so I'm not worried about bed space. I have a 34' Montana with an extended pin box with plenty of bed rail clearance. The big question is does it interfere with the pin box, are there any striking/denting hazards that I'm not taking into consideration? Will it interfere with hitching/unhitching? Does anyone have any real world experience with the V box v flat box with recommendations? Thanks for the advice.
