I am wanting to have a slide topper installed on our 2016 225 RBS Shadow Cruiser. My problem is, I don't know if I should trust the selling dealer to do this. When we bought the trailer we wanted a larger "helper handle" installed since we both have knee problems. Well when it was installed the tech ran the screws THROUGH the interior wall !!! They did cut them off after. I DO NOT want the same problem with the slide cover. So what say the Forum ? Don,t trust local Camping World either. Anybody have this trailer with a slide topper installed ? Thanks in advance, Dave
