The Tundra DC has a payload around 1600lbs which includes full tank of gas and 150lbs for the driver. Reduce that number by anything else (drivers weight over 150, passengers, pets, gear etc) that you put in the truck to find remaining payload. Don't forget to subtract the weight of the fiver hitch as well. What's left is available for pin weight. The average fiver pin weight is 20% of the loaded trailer weight.
payload = 1600lbs
50lbs (driver is 200lbs. 200-150 included)
150lbs for wife
50lbs for dog
200lbs for hitch
Leaves 1150lbs of payload for pin weight.
Average pin weight of 20% means max trailer weight of 5750lbs LOADED
(5750X 20% = 1150)
If you pack light and only put 750lbs of stuff in the trailer you would need to find a fiver with a delivered weight (not dry) of under 5000lbs. I don't know of any fivers that light.

This is almost exactly what was in the info i posted, lol. But you get the jist, basically, like markbrit said, the tongue weight or pin weight cannot exceed the gross payload rating. And if you already have payload in the truck (passengers, normal sized american drivers, children, cargo, etc) then you must subtract that weight from the gross rating to get the remainder you have left to use. The whole idea behind a fifth wheel trailer is to put more weight over the axle, as opposed to behind it, which acts like a lever, and gives you the "nose up" stance. However, half ton trucks do not have high enough payload cap. to make it worth it. A ~5,500 lbs fifth wheel is a small fifth wheel. You may be better off with a conventional TT with a weight distribution hitch.
