Towing with 5th Gen

This weekend i got to tow my 5th gen for the first time..any suggestions on springs for the rear i did use the WDH and the Tow Pro electric brake controller little sways here and there but mostly because of the wind and driving at 55 MPH

 

What is the tongue weight with the weight in the trailer at the time of this photo? We tow 5000 lbs on stock springs with airbags and never see sag like that even before inflating airbags. Get to a scale and confirm. If I had to guess, I would think you had 800 lbs on that tongue. If that is the case, moving any load within the trailer back and over the axle should help. Keep the tongue weight in the 10% range.

 

Check out this forum, it has a lot of great insight, tips, tricks and advice: https://www.4runners.com/forums/towing.64/

 

my understanding on the Coleman lantern 17B its about 380 tongue weight DRY and the trailer alone is 2900 dry as well i add like another 100Lbs or so to the weight

 

Your WDH is not dialed in correctly and you are in danger of a sway control problem. It looks to me like you are way overloaded in the front of the trailer. 60% of the weight in the front, 40% in the back.

A WDH needs to be set up, not just attached. Get the owner's manual for your hitch and go through the setup process.
