IIntroducing the new compact, Travel Trekker 40auxiliary fuel system! This innovative 40 gallon product works great with most any full-sized diesel truck. That includes half ton pickups with Utility beds, those equipped with a RamBox(R), and those equipped with a factory 5th wheel package. Additionally, it will fit many mid-sized vehicles, is baffled to minimize fuel sloshing and will even fit under most tonneau covers. The TITAN Travel Trekker 40 is made of our famous military grade, cross-linked polymer-- tougher than steel and more durable than aluminum. We routinely test our products using state of-the-art computer simulation as well as actual, physical drop tests. We fill our tanks completely and drop them 30 feet onto a steel plate---never losing a drop of liquid. Our legendary products are so tough and well-proven that we back them with a Lifetime Warranty! There are no welds to crack and fail, and if you ever accidentally run your gooseneck hitch into your Travel Trekker you'll find it springs back into shape. Occasionally, a little soap and water, and perhaps a little spray furniture polish is all you need to keep your tank looking new. With one touch of a button, the remarkable TITAN Electronic Controller pumps fuel from the Travel Trekker 40to 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 Travel Trekker 40comes with all necessary installation components and detailed instructions. Whatever your passion, we'll help you fuel it!
