Well I am please to have my Pop & Lock 5300 installed on my Tacoma. Everything was very easy to install. The only real problem I had (delayed me for 2 minutes) was getting the locating tab on the rear panel out of the metal frame hole (just above the handle area). I didn't want to break it, although it would have no affect on performance had I broken it. Installation of the camera was painless although I had to use a small drill bit to open up two guide pin holes just a little bit so it would fit well.
Operation of the handle is nice and smooth as well as the locking was smooth. I used a little blue locktite on the two mounting bolts (used the two bolts holding the camera in place), which also inhibits corrosion (present on the old handle bolts).
Mechanical quality appears fine. Visual quality, well I'm not too happy with it. The plastic is a cheap looking high gloss plastic which scratches very easily so it shows wear very quickley. The half dozen times I opened the tailgate showed several scratches on the handle. I would rather have a matte finish.
Purchased the unit from TruckAlterations for $47.00 delivered.
