Thanks all for the feedback. I believe the trailer hitch is factory. How can I tell if the hitch is a weight distributing hitch to confirm?
Importman is more versed in towing and will probably chime in with some better info, but hopefully this helps:
This is the v8 hitch. Toyota calls it "weight distributing" but its really just a frame mounted hitch. However, this is a key ingredient to a weight distributing hitch setup. Your 05 should have it, but just check its not a crossmember hitch like the v6s and early-early v8s
Next ingredient is the weight distributing hitch itself. The arms and chains reduce the up and down rotation at the hitch, while also directing force into the frame of the vehicle and up to the front wheels. The sway control is the thing labeled with the CURT in both these pictures, and acts like a shock for the rotational axis. This helps to make your setup drive more like a straight truck on the highway, where you're not turning a whole lot and don't need the trailer to rotate freely about the hitch. I'd suggest watching a video on how it works, it kinda clicks if you can see the trailer lowered down onto a vehicle with a WHD vs a conventional hitch.
