OK gang. Been awhile since I asked a question. Over the last couple of years, I'm noticing more and more that I am getting leaking into the rear bed. Mainly between the first panel and the back wall of the Avalanche. Living in the Pacific Northwest, rain is an issue (for those who don't know it, we get a lot...) So, since my Avalanche is now nearly 17 years of age, do I need to replace all the rubber seals on the panels? Oh, and panel 2 sometimes gets waterlogged. Thanks for any advice or adjustments that you suggest. I need to keep my Costco runs dry until I get them home!
