My current set of timbrens have approx. 55,000 miles on them. They are always ready when you need them with no adjustments required. I paid $179 for the DR2500CA kit, put them on in 15 minutes(without the optional spacer), and never touched them again. Without the additional cost of an onboard compressor, air bags would never work for me. Timbrens are much more than a bumpstop.
I've had airbags on 2 trucks and no problems. I like being able to keep the loaded heigth the same as empty, for the steering and headlights. I also have air adjust Rancho 9000s and in-cab air for both. The shocks are equally useful for tuning out rough roads. I would do it all again, exactly the same way. Craig
Can someone help me understand why you'd want to adjust the pressure on airbags while traveling? Sure, I can see maybe in the beginning as you're trying to figure out what is the best pressure for your load, but the pin weight can't vary much when pulling the same unit for years, so I would think once you figure out the airbag pressure you like best, that is the pressure you use while pulling. So what's the justification for the significant additional expense of an on-board compressor and controls?

If you've ever driven in Mass....you will know why it needs to be adjustable.
All bridge abutments are not constructed the same. They have the same principal...but different construction. Most bridges in Ma that I have been across go something like this...Up to the abutment, down to the edge of the bridge, up to the center of the bridge, down to the edge of the bridge, then up and over the abutment back down to the level road surface.
What this translates into is a healthy porpoise at 45 or above.
This doesn't mean that Ma is the only place that builds bridges like this.
While I am traveling, I add air when we run into multiple bridges like this and dump it when on the flats for long periods.
Still liking the Super Springs. Easy install and turns a 2500 into a 3500 but only work when a load is on them. No load, still have the factory ride.

On rougher roads, I let out a little air to allow for more travel so the 5er doesn't have to take so much hammering. Then I play with the shock psi to get the dampening right for the travel. On really rough roads, I can make more improvement with the shocks than the bags but together, they are fabulous. Craig
I've had two different bags at different times. Both leaked after 2-3 years. I've also tried the Timbrens on my current 2500 2wd truck and they limited suspension travel with a short compression and a violent rebound. The timbrens on a 4x4 same truck were 4" longer and worked great.
I had to go with Supersprings for my particular trucks suspension issues. I now have my stock compression/rebound suspension unlike the bags or Timbrens gave this particular truck.
One size don't fit all so IMO the best input is from folks that have a truck/suspension identical to yours.
