Multiple Elk hunting trips over the last 2 seasons and my unknown camper is holding up nicely. I just removed the CO2 lifts and replaced them with (4) 12v linear actuators. Much easier than dealing with CO2 leaks, pinning, stopping the closure to tuck canvas etc. Here's a couple pics from Oct 2014 that shows the angle aluminum header, moved front lifts to the inside and the great job my mom did on the new canvas (black tape eliminates rub spots from the door when traveling). Plan to plug all the no longer needed drilled holes with fiberglass and paint it in a couple months when it warms up. My son did this Elk & Salmon decal I'll paint on it too.
