Get the H2
What ever you get, get the HD version with a little extra G.C.
There are a couple places listed in the Fisherman Mag for cooler racks. The one I have on my Bronco is big enough that a 150Qt swims inside of it and a 196 would easily fit, it's also made out of Iron and is high enough that it doesn't plow in the sand. It also has little to no effect when I drive it most of the way to work, 50+ mile drive each way (the people tend to get out of your way too)
