Titan Tanks is about the only aftermarket fuel tank company you'll find boasting on their website that their tanks are not the most affordable on the market. They make that known because they're so confident in the quality of the tanks that they make it clear the higher price is totally worth it to the consumer. Titan Tanks are made of a military grade polymer and their tanks require no maintenance whatsoever. Titan Tanks don't delaminate, don't corrode in long term contact with diesel fuel, don't condensate moisture, don't develop weld cracks (they're not welded) and don't weigh down your rig (they're lighter than other tanks).
