It would take some doing to get the batteries out as they won't fit up through the winch bay openeing with the lugs screwed in so inorder to remove or steal them they would first, have to know there in the bumper, second, unscrew the diamond plate cover I made (with thick rubber mat hanging of the back between the intercooler and terminals) third, remove all the wiring, fourth unscrew the terminals, fifth, unscrew the tie downs on both sides of each battery, and sixth if they did 1 thru 5 they have them

probablly just as easy to take them from the fram rail or bed of teh truck but I don't know many people who have come out to there rig to find the batteries stolen its usally a stereo, CD's, Money, CB, or something of more value.
If I hit something hard enough to push that big a$$ bumper in that far then I have other problems that I need to worry about.
As far as wieght, I wanted to keep the wieght as far forward as posible for sledpulling, and its my daily driver it handles very good.
I am not saying its good for everybody, it's great for me :-laf
