Now a new, better concept in auxiliary fuel systems: The TITAN Travel Trekker is made of our famous military grade, cross-linked polymer--- tougher than steel and longer lasting than aluminum. Its durability is legendary. We routinely test our tanks using state-of-the-art computer simulations as well as physical drop tests. We fill our tanks completely and drop them 30 feet onto a steel plate--- never losing a drop of liquid. They are so tough and well-proven that we back them with a Lifetime Warranty. (50 Gallon TITAN Tank)There are no welds to fail and if you ever accidentally run your gooseneck hitch into your Travel Trekker you will most likely find it springs right back into shape. Also, soap, water and perhaps a little furniture spray polish is all you need to keep your tank looking new. The Travel Trekker is baffled to minimize fuel sloshing and compact enough that it can be installed in full-sized pickup beds without interfering with most in-bed hitches and tonneau covers. With one touch, the remarkable TITAN Electronic Controller transfers fuel from the Travel Trekker to the vehicle's primary fuel tank until it is automatically stopped by the controller or the button is touched again. The controller monitors and reports the fuel level in the auxiliary system at all times. Controller installation is simple and never requires cutting into the vehicle's wiring harness which could affect the manufacturer's warranty. Fuel is pumped from the top of the tank which is safer and more environmentally responsible than gravity flow systems. The system comes complete with all necessary installation components and detailed instructions. Whatever your passion, let us help you fuel it!
