I got the decked system, Not overly impressed.
You lose a LOT of space. Probably 50% (esp around ammo cans: tons of dead space)
You lose access to tie downs
Got 2 x crossbox. Put one at back of wide drawer, When i got to destination it had toipped up and couldn't open drawer, had the take off...
I just bought an IKamper mini for my 2020 Ranger (4 door). Ordered RCI universal rack but cancelled because they said 6-8 weeks lead time: it's a universal rack for Pete's sake and they carry no inventory. Ordered Zroadz access overland (ships on 30th, so another week or so before I get it)...
I bought the decked and not overly impressed. It wastes a TON of space, especially behind and besides the ammo cans. they could easily be 50% bigger in volume
