Is your suspension stock?
The truck is pretty much stock, other then the TRD Off Road Wheels and 235/85R16 BFG AT Tires. The truck only has 64K on it so I am suprized about having drivetrain problems. The truck is more of a daily driver, since I still have a TJ for off road adventures.
The sound vibration is definately coming from the drivetrain. Since, I can feel the vibration through the streering wheel, I think its coming from the front end. I usually notice the problem on secondary streets at between 35-45 MPH and I can not get the problem to duplicate through driving style. I have visually inspected everything, but found nothing of significance.
So, I have turned to Expo Forum for a virtual diagnosis.

Sounds very similar to the vibration problems I had after installing the OME suspension, and the resulting lift of the truck.
I would guess that it is in the two piece drive shaft, at the carrier bearing. You could try dropping the carrier bearing a little. In my case I found removing the carrier bearing drop kit and raising it back to stock made the vibration mostly go away. But that was a very odd solution as most Tacoma's need the carrier bearing dropped when they are lifted.
Try loading the bed up and getting a different driveline angle in the rear, and see if that makes things better or worse.
Let me know what you find.

I know some people were having this vibration problem even with stock suspension. But if it has been driving smooth until now it does sound like something has worn out.

try this first
Try rotating your tires from front to back first. Don't change sides.
Could be cupping on the tires from Toyotas fine alignment job from the factory.

With 64K miles on it I hope it is not the "factory" alignment still. I would start with the simple stuff. I agree with Jeff swap the tires front to back and see if the vibration changes, not resolved but see if it changes. Next I'd grease the driveshaft fittings and see if that changes it. Also-are you applying the brake when the vibration happens ? Have you had the trans fluid or diff fluid changed recently ? Does the Tacoma have a rear LSD ? if you had the rear diff fluid changed and they did not put the LSD additive it will cause a vibration.
Weekend update:
The problem did not occure over the weekend, and I put a quick 120 trip on the truck. I purchased the truck used with 27K miles.
It has had all of its routine maintenance done by either Toyota, and an independant Toyota specific mechanic.
The truck has had 2 alignments in the 40K miles I have put on it, and the tires show no sign of cupping after 12K miles. Since I have owned the truck, I have had it aligned twice.
When the vibration/sound occures, the truck is usually coasting, without the brakes applied.
The frustration is that I can not reproduce conditions to make it happen, so it is currently a true intermitant problem.
