I also have the BakFlip and absolutley love it. No issues what-so-ever... The only thing you have to remember is that you have to close the tailgate 1st before you close the Bakflip... otherwise you'll hear a not very nice crunch sound... I did... but I've only done it the one time.
Bakflip G2 , no real issues , didn't expect water proof so I wasn't disappointed with a few drips . No issues with snow , only thing I've noticed is that some part of the mechanism is nicking the rubber when I fold it up . The shop that I bought it from I'd never do biz with again . I like the RollBak or Bakroll with the tonno look and metal slats .
