Ya', there is no need to fiddle with it if you don't want to, set it and forget it.
As far as air bag reliability - OTR trucks put literally a million miles on them. Yes, you have to make sure your lines and bags are protected. But you can have a tree rip a heater hose off too (I know from experience). It's also not a bad idea to have a shrader valve around so you can just disconnect the whole air system and just fill up the bags individually in case something happens to the system. If you're really paranoid, carrying an extra bag might add to piece of mind. But that's up to you. Oh, and I'm not a fan of the reliability of quick connects. They work, if they're good ones. At work we cycle a leak tester 2,000 times a day with the swagelok style connectors - the metal ones, the plastic is crap. If we have any leaks in the system we get a false failure, which costs us production. If we had lots of leaks, we'd loose big money. So they can be good, but if I'm not messing with the system often, I'll take a good ole fashion compression fitting. If the top of the bag is secure, you could actually run hard lines for the majority of the system.
If it was my set-up, and I didn't have the cash to fittle with a fancy control system, I'd only adjust it for a few reasons and they won't be real often-
1. Dump it all the way down to make entry and exit easier - which on that beast is going to be difficult no matter what!
2. Raise it to get a better aproach angle or breakover angle at a paticular obstical. Again, if I had bags on my ride, even with 37's and long travel shocks (I could probably raise over 8" from ride height) at max height I still wouldn't have your approach angle.
3. Adjust for a heavy load. I'm guessing you don't use it for hauling bags of dirt from the home depot. So not likely an often deal for you.
4. Setting ride height for different terrain. Low ride height w/ 30% compression 70% extension for crawling, bump it up to 50/50 or 60/40 for faster moving open stuff.
5. Add the cross over for no other reason than "Why not".
Hopefully the PO set the system up well. You can always add a bigger tank and a second compressor if you really find yourself playing with it alot.
Assuming you're locked front and back, I want to see the trail that you can't do WITHOUT playing with the system to force articulation. I'll be taking the bypass on whatever obstical that is!
One last thing- if the airbags don't have internal bumpstops (some do, some don't) make sure you're bumpstopped to protect the bags. I beleive Cody C was having issues with that.
