4Runner rear axle upgrade: air bags or???

[DakotaSue]

I will be picking up an Escape 19 at the end of February. I am towing it with a 2003 4Runner, V8.


The 4Runner has heavy duty shocks and Curt hidden hitch to allow for the WDH that is part of the Escape 19.


Any thoughts on whether air bags should be installed to help the load? If so, recommendations?


I was towing a 17 ft. Liberty Deluxe prior to hitching the Escape 19 without any issues.


cheers

I would say no air bags if you are using a WDH. See how it levels out and see how it tows with the WDH before considering any other mods. I used air bags on a 4Runner without a WDH and liked them.

Thanks Viajante,


That is encouraging that I may not need air bags. I will know when i tow the E19 back to California.

I had a 2017 4Runner pulling an E17B. I used a WDH but not airbags. I read a few posts about people that rely on airbags get into trouble. They blow at the worst times. If you rely on airbags, take 2 extras and be prepared to change them on the side of the highway.

I can't agree that this is logical, neccessary, or practical advice. It is not like blowing a tire.

If an airbag leaks or ruptures your vehicle still has fully operational springs and shocks. You might replace the airbag at the next practical time. The airbag assists the springs and shocks, it doesn't replace them. And the tongue weight of the trailer shouldn't exceed the capacity of the vehicle even if airbags are used.

Will post a trip report on handling after I pick up the trailer and travel back to Goleta.
