Air bags are not?

TNRIVER...I tow a 6K dry 25 ft. Keystone Outback with an '08 Tundra 4X4 using a 1K/10K Equalizer...so we're pretty similar in set-ups.

I had Airlift 5000's installed on my truck for several reasons:
#1. To try to minimize some pretty horrible porpoising on some bad sections of concrete-paved highways we frequently travel. End result, while the bags helped somewhat, I found I needed to CORRECTLY adjust the Equalizer, carefully following the factory directions and doing careful measurements. That made ALL the difference in the world.

#2. Sometimes, even with the WD bars in place, it just settles the ride down on bad terrain and especially those bad "Bump Ahead" events you occasionally find on highways.

#3. To be able to tow/move the trailer without the weight distribution bars in place eg. negotiating tight corners and backing into tight campsites, traversing sharp/steep inclines, and getting into my drive without scraping the bottom of the hitch post on the pavement (high street crown + deep curb gutter + sharp driveway apron incline).

I consider them very useful, under certain circumstances.

I went with Timbrens on my Tundra mostly because of cost and ease of installation. Air Bags have all the advantages BGood pointed out and are probably superior to Timebrens but I've been very pleased with the Timbrens.
