We've had our EB over about every jeep pass in Colorado (Engineer, Cinnamon, Imogene, Tip Cup, etc.) with no issues. Last year I added airbags on the rear for just a better general ride level, but was also told that if I ever needed I could get about an extra 8" of rear height if needed. I have also noticed improved 4wd handling because there is less rear body bounce. Our custom design would not fit inside an RB, so often your design will guide you unless you are going with one of the standard designs. We also have the PSD diesel, so with the additional torque and less power loss at high altitudes we see no performance loss fully loaded at over 11,000 pounds.
