I bought a used topper that came off a 2014 Tundra. I have a 2010 Tundra and when I put the topper on there was a little bit of an overhang. I did not think anything of it. After driving it on a rougher road I noticed rubbing on the cab and feel like I need to move the topper back, creating even more of a gap. Is this fixable? Or should I sell and move on?
