As far as ext cab long bed trucks go the Tundra has one of if not the shortest turning radius in this class, so I would say apples to apples it would be the easiest to park and drive. That said there is only Ford and Toyota that offer this configuration. In recent years it would seem the traditional 8ft bed that was so common for decades has lost a lot of its favor with the public. So I would suspect that is why you are seeing such a good deal on one.
Totally agree on the extremely tight turning radius. My wife and LOL'd during the test drive, with the nice dealer lady, because I kept cutting full-lock circles, in a parking lot, because I couldn't believe how tight it turns.
There are two areas where the DCLB could be considered "cumbersome," IMHO.
Until I learn a particular drive-thru location, I have to lower my right, outside mirror, and keep an eye on the RR tire, so as not to scrub/jump the curb. This means turning EXTRA WIDE, meaning sometimes I have to open the driver's door and stand on my wide-ass, OEM running board, and "pilot" just how close I can get to the curb with the LF wheel, to give the RR wheel max. clearance (in a right-hand turn).
2. Parking Spaces.
I'm "allergic" to door dings. And hit-n-runs. In a metro area, (some) of the parking spots are just too ****ing SHORT. So IF I pullled/backed straight in, 2-4 FEET of Truck are sticking out past the vehicles on either side (if they're small cars). So, sometimes I do the "dick" thing and angle across two spots.
BUT--I try to only do that waaaay far out where no one is parking anyway, because I don't want to get "keyed." Because "MuriKKKa."
I'm considering having some signs printed saying "Extra-Long Truck. Parking Angled for SAFETY." (Or words to that effect--suggestions welcome--SNARK is not.)
