Fave hydraulic leveling system?

I had the BF system dealer installed 4 years ago. It has been a superb system. I had one event that I could not get the system to function. Called the 800 number and got an immediate answer from the tech and he talked me through the correct procedure. I have called several times since then for various reasons and always got through to the tech quickly. I could not ask for better customer service. The product is excellent and I would do it again without hesitation. Good Luck.
