Those Extang, Trailseal, and some others looks well made from the pics in their site, but I had this question. I notice the biggest of any of these tailgate seals seems to be 3/4". The lower gap in our later Ram pickups seems even bigger than that...maybe as big as an inch...a little hard to get any measuring device in that gap when closed. Even if the seal closes the gap down to 1/8" or 1/4", that's still going to let a lot of dust in. Dust is my main concern in areas that I drive on dirt roads. Anyone have any pics of the Extang or similar seal in place where you can see the gap or any light passage perhaps? Someone else mentioned overhead garage door bulb seal as a possibility, but I haven't checked that out yet. I'd even be up to using stainless screws and drilling the proper material in place if it guaranteed a decent seal on the bottom. The sides and latch points look easily fixed with the Extang and some other creative measures.
