I almost bought a racing version of this VP fuel tank as it was considerably cheaper but then I read the reviews and saw the other one wasn't me I have no back or butt. I almost overlooked it as nowhere does it say it was just 3 sheets of aluminum (reviews aside) and you would assume it has both as its main function is to hold fuel canisters. I'm glad I went for this one because I'm sure it's a lot heavier because it's a diamond plate and a fully boxed block with a base. Much better.
