My buddy tows a ~3500K trailer with his '03 V6 4x4. He's lucky to hit 45mph on the hills, and he's 1500 pounds under his max weight.
If the DRY weight is 4200 pounds, you're easily looking at 5000-5200 pounds for the total weight if you're putting any gear in the trailer. Then add in passengers, etc... in the vehicle, and you're quickly approaching the MAX gross weight (truck + trailer + cargo + passengers).
I don't plan to tow anything heavier than 3000-3500 (total, with gear/water, etc...). Yes, that's a fairly small trailer (a tent trailer), but it's also a fairly small truck doing the towing...
It's the GVWR of the truck only (not the GCWR - truck + trailer + cargo + passengers) that is usually the limiter with the Tacoma. The payload is just too low, especially with the 4x4.
The problem with the Tundra is that in the 4x4 configuration, it really only adds 200-250 lbs of payload, not enough to pay the price to upgrade IMO. There are other half ton trucks that add much more capacity.
