tank material ?

[rallystyle]

i am looking at a ricks tank. i see that you can now get them in aluminum and save about 35 lbs vs there SS tanks. the real question i have is about the durability vs the SS tank. my car is stored out side in the winter and the roads up here (alaska) suck. i dont want to have to worry about the tank having problems and corrosion problems. i plan on going with a vaporworx setup and just dont want the weight.
