Sliding Rear Window // MX4
 

has anyone had any problems with the bakflip mx4 and their sliding rear window? my local accessory store said they tend to lean towards the ultraflex over the mx4 because id doesn't put any pressure on the back window. they said they have seen some sliding window problems that they attribute to the mx4 leaning on the window.

not sure if i believe it but i figured id see if there was any first hand experience here before i buy one.
