We just returned home from having some work done at Lippert, its a 400 mile round trip. We have noticed ever since we arrived home that in the evening time we get a noise coming from the off door side front leg area. It certainly seems to be temperature related cause I can walk in the bedroom area in the evening to make it occure but during the day it does not happen when I walk in the same spot. We do have level up and we did have the fix fluid installed at the Rally for the popping noise. Wanted to get everyones opinion on this issue. Thanks, Bobby A
