I am considering up grading my Chase mini packs to full leafs (from any of the big three suppliers - although I like Lorenz's dual purpose leafs). However, I have an ARE top and Bedslide plus tools, recovery eq. , etc. that keeps about 450-500# in the rear all the time. Add a little cargo or a light trailer and it will squat the rear a little. I am afraid the full leafs would cause the ride height to suffer at light loads (or empty) and not be necessary since my normal rear axle weight helps to smooth out rear ride. Of course, air bags with full leafs would be the ultimate, but I'm not sure the cost/ benefit would be worth it to me.
