As far as the sides go I think the inside plastic fits pretty close to all the body panels and there isn't a whole lot of room there before you will be getting in to the wheelwells. On the tailgate ... even with all the cutting and welding I have done on mine I still have not had that back cover off to see what kind of room there might be there. It could be a good idea tho'!
The only thing I can tell you is to pull the cover off and see what kind of room you will need for that compartment and if there IS room ... start cutting!! Just make sure if you go for it to take lots of pics and make sure to post them for the rest of us!!!
It would be a cool mod and you would be the first!!
I do know there are several different sizes to choose from. You might also try some of the other boating supply stores online and see what other kind of cut-in type compartments are available.
