I have the Heco based roof lift system on my Sun Light Sky Hawk...also have a roof air. The roof air is a Coleman Mach designed for pop ups, it's a bitch getting the roof up, but I have had no issues with the roof to date. I'm not easy on my truck, chased the Baja 1000 and the Mexican 1000 among numerous desert races. A Baja peninsula run is probably equivalent to a couple of years of normal wear/tear.
