I am thinking about upgrading my rack system because I have been consistently overloading my current setup. The best size for my situation is the big ARB alloy rack, #4900010M, 87"x49". I want to mount it directly to the top of my cab-high SnugTop fiberglass shell. So far, so good. ARB does not have any mounting hardware for this type of mount, they have no drawings available that might show me mounting or attachment points, and they have no photos on their website that show the bottom of their racks. I have called around locally and none of the dealers I have spoken with have any ARBs on display for me to look at. So, has anyone done this type of mount with an ARB, or does anyone have pics of the underside of one of their alloy racks? The fiberglass part is easy, and I'm not worried about weight or leaks, just how to attach suitable mounts to the ARB rack. My alternatives are a welded steel lumber rack (overkill), or a SmittyBilt Defender rack (cheap, readily available, and easy to mount). I like the ARB idea, despite the outrageous price, because the overall size is right for my needs and it's lighter than than the Defender.
