What kind of isolator did you use? It looks like the one I had for my last genI... it worked sweet. One time on the trail, I went to crank the truck over (my only auto), and couldn't turn the starter - pushed the button to use both batts, and it was enough cranking amps to get it turned over again! Of course I went home and rebuilt the starter, but I was able to get home!

Dual setup is the cats meow! Great placement! You guys don't have much room under there...
