I got my Literider and PopLock today from Truckalterations.com and thought I'd post up some pictures and my initial thoughts. First off, truckalterations is an excellent place to buy from, they processed the order tuesday or weds and I had it delivered within 3 days. Free shipping and prices you can't beat, I'd highly recommend buying from them! Total price with Literider, Trailseal, and PopLock was $340
The Access Literider was fairly easy to install, it took me about 2 hours total working alone to install, just needed my drill and a couple of sockets. I bought the trailseal kit as well, I used the gasket along the front edge of the bed and along both vertical rails in the rear. The only thing I found different with my first gen vs the instructions online and other pictures I've seen is the rear of my bed is curved, so Access sends a pair of short sections of gasket to seal up under the rail on both sides. The first rail I didn't do it well and ended up using some clear silicone to fill in the gaps, the 2nd side went better.
I don't have any other tonno's to compare it with, but it seems pretty high quality and very easy to roll up and unroll. I had to take it off and re-install it a 2nd time because I forgot to tuck the straps under the front rail so that the long ends hang down into the bed. I tested it after install with the hose and everything stayed dry, I'll post back after I've driven around a while and been rained on for real.
The PopNLock was a pretty easy install as well, but if you've never unbolted your tailgate handle be warned, spray it with some rust release first. I broke off one of the bolts without really trying at all, so I had to drill it out and rigged up another bolt to work. Everything seems to be holding together so I'm keeping my fingers crossed. It's a little cheesy and won't stop a determined thief, but it's a deterrent.
