Backflip HD issue

Oi

So, I have installed the Backflip HD tonneau cover. One issue I've noticed thought and wondering if anyone else has seen this. After install, near the tailgate, the tonneau rails are actually raised slightly so not completely sealed. I'm tempted to loosen the rails and do the ends first to see if it resolves the problem. Has anyone else come across this? It's only about a 1/6th of an inch raised but just enough to piss me off. I loosened the nearest bolt and pushed down on the rail to see if i could get it flush but no luck. Maybe the bolt i fastened first, near the cab, was the wrong approach. Let me know your thoughts! This forum rocks.

 

You are typically supposed to tighten all the bolts at the same time to avoid bowing.

 

I'll try redoing it
