Whats the best way to determine whether the cover is adjusted correctly?
I havent messed with the adjustment screws yet, the cover seems pretty tight but Im wondering if its too tight.
I dont want to overstretch it or ruin it.
Its the LoPro cover

 

I've have the Lo Profile Truxedo on my 2004 Styleside 6.5 ft over 3 years now with no problems or dissatisfaction whatsoever. After installation, I just followed the adjustment screw settings according to the owner's manual installation instructions which I found at www.truxedo.com. I have not readjusted the tension setting since that initial installation.
