I crawled under our 2008 Bighorn 3600RL, and took some pics of my springs. They are Lippert 7K and they look like they are overloaded, flat and have some reverse bow, but I didn't see any breaks in them. Please take a look at the pics and tell me if this is normal. We purchased the unit in May of 2007.
Steven...if the flat springs in the pics are on your rear axle, you might want to check how level you are. If you are setting "pin high", you are transferring too much weight to the back axle. We had the same situation, had our rig weighed, and determined that we were 500 pounds heavier on the rear axle than on the front axle...thus causing the flat springs.
We check and we were actually several inches high in the front, even though it did not look like it. We adjusted the pin box and the hitch, bringing the unit as close to level as possible, and we now have less than 25lbs of difference between the two axles....
