I thought about something similar. But from what I read on reviews and all that. I have had trifecta before and never had issues. so I decided to stick with true/proven cover based on my experience.
I'm getting my truck sprayed and already got the mat. Since I have the experience with spray-on. Things LIKES to slide all over the place. Thats why I got Ford mat to go on top of spray-on to stop the sliding. As for tonneau, go with extang trifecta 2.0. They're best.
