We completed our trip about a month ago after traveling around 5k miles in our motorhome (2003 Rambler Cummins ISC 8.3). After having your product installed, we immediately recognized a smoother, better starting, more powerful motorhome. Additionally, probably the most important to me, was the comfort knowing that I would always have a positive fuel supply feeding the main injector pump! Since the stock design injector pump draws or sucks the fuel from the tank, which is about 30 ft away, the AirDog pump removes this design flaw by providing fuel under pressure, which is a great thing! Another benefit is picking up about 2 additional lbs of turbo boost, which is always a plus. Overall, a GREAT product that I would highly recommend! Thanks again. P.S. Lance and his team are KEEPERS!

My Coach is a 2001 Holiday Rambler Endeavor with the ISC engine, the Cummins 8.3 liter. This is similar to several Monaco models of that time period. Our first significant travel since installation of the AirDog system was in November and December 2021. From NC to Northern VA at Thanksgiving and then NC to Southern Florida and back in early January. Probably 3,000 miles on the system. First, the coach performed flawlessly the entire trip. Of course we did a few miles test run before hitting the road to check for issues like any leaks, etc. Your kit is excellent and instructions are straight forward. When I did have questions, Lance was always quick to get back to me. The technical aspects of the installation were not difficult, but getting to some of the connections was, due to the tight quarters (trying to get two 1″ open end wrenches on JIC fittings where you could barely get one hand into). My installation was probably ideal as the AirDog went directly where the previous primary fuel filter was and I was able to use the existing fuel lines. They were Parker hydraulic hoses and are in good shape in spite of the coach being 20 years old. Improvements are smoother idling, better acceleration, and although I need more data on fuel consumption to make a firm claim, we got 10 mpg on the return trip from Florida towing our Jeep. Never have we seen above 9. Cliff Bass Halifax, NC
