Maybe this should be in the Diesel section but it was obscure so here it is. I am searching around for battery box ideas in my manual HDJ80. I am lucky because there is room for two batteries behind the air filter if you do it right given the placement of the washer fluid reservoir. I have done a few searches for battery boxes and haven't found anything on some good box mount ideas. I see all the nice holes where I could build a mount but there are no really great points. Anyone do this? Pics?
