I have an Extang Full Tilt on both of my pickups and I love it. The bed can be accessed in 3 ways.
The cover can be lifted (It is supported on struts) to load/unload the bed if the cargo is low enough to be covered by the tonneau
when in motion.
The tonneau can be unsnapped and rolled forward to allow the bows and rear cross rail to be easily removed giving full access to the bed for bigger loads.
The entire cover can be removed/installed in tact by one person in about 30 seconds.
I have had one on my 2009 Tacoma Access Cab for about a year. I use the truck for everything including towing a travel trailer. The cover holds up well and has not stretched. I also have a 1966 Chevy 1/2ton show truck and I have an Extang Full Tilt on it.
The only downside is that the cover comes disassembled and it takes a bit of time to assemble everything properly. The instructions are good and easy to follow except for attaching the tonneau to the front rail. That is a bit tricky and I screwed up on both of mine until I finally figured it out (With my wife's help !!). The entire front of the tonneau fits into the grove on the front rail and, once you get that figured out, it slides in very easily.

If I ever change pickups, I would definitely use another Extang Full Tilt on it. Also, Extang customer service is great to work with.
Hope this helps.
