Trailer Pull

I am thinking of setting up a small trailer <4000 lbs on my V6. Any suggestions for strengthening the rear of the Runner appreciated. Factory tow package in place.

Thanks.

You're getting close to the limit, so maybe airbags in the rear springs would help. Have you hitched it up to see how much the rear sags?
 
You should not have any problems with such a small trailer. The factory tow package comes with the larger diameter sway bar (21mm vs. 17mm) and provides some additional lateral stability.

If you have any issues with a light trailer, it will be the fact that such a light tongue weight might cause a "teeter-totter" effect on the hitch ball, causing the rear end to jerk up and down on uneven roads. Obviously, load the heavy cargo towards the front of the trailer.

Lateral movement can usually be managed by increasing tire sidewall stiffness, by using a higher tire pressure (read your sidewall regarding PSI) and/or using a light truck (LT) or C-load rated tire. In addition, your suspension bushings have got 7+ years of wear on them, and may be worn or soft, that may create some rear end wiggle.

Check the condition of your brakes.

Click the shift knob to "4" if you are traveling over repeated inclines. It will be easier on the transmission if it isn't switching back and forth between 4th and 5th gear, and the engine will be maintained in a slightly better powerband.
 
give yourself more time to stop, plan ahead, account for the total weight of the vehicle and trailer, people and belongings included, it will make a difference.

the motor, trans, and drivetrain can handle the load, so long as you plan ahead and don't stress the brakes too much.
