Your ball should be 2 5/16". On the coupler on the trailer's A-frame, the size is stamped there along with the coupler's weight ratings.
Experienced trailerists will all tell you that WD is pretty much a must have for safety and to treat both the truck and trailer properly. The short form is that too much weight on the truck's hitch lightens the load on the front axle to the point that steering capability can be lost under some circumstances. And, depending on the axle rating of the truck, it may be too much weight. Not likely with the T-1950, but WD gives a stable rig regardless of conditions.
Your best bet is a Reese trunnion style WD system with HP Dual Cam Sway control. For your T-1950, 600# or 800# trunnion bars should be fine. See www.reeseprod.com
for detailed information and product choices.
Since your truck is 4WD, find out what the height of the receiver is above the ground and the height of the coupler from the ground. Both measurements should be taken on a flat surface. The 4WD truck may sit high enough that you'll need a shank that drops lower than the standard one.
If you purchase your hitch system from a reliable trailer dealer or RV shop, they will help you determine the correct shank.
