i ran unloaded with the bags at 60psi for a few days til i remembered. the ride wasn't as annoying as the view of the rear end being jacked up high.

mine have internal bumps, i thought most did. i've definitely bottomed the truck a few times with no issue, didn't seam different than before. no bumps can damage the bags, i'd spend the money to get them

i'm 98% sure i got the air lift kit from amazon, that price looks right. super easy install, all there ... my only complaint was that the exhaust heat shield rotted n fell off in the the first winter.

i installed the 2 fill valves inside the gas door, just drilled holes in the plastic surround in there. would do it again. also, be careful filling, they fill FAST.
You probably didn't notice the ride difference as much in your 2500 cuz it's already stiff as hell. Mine rode pretty damn rough from the get-go and had high enough load capacity I never put helper bags on it. There were a few times when I was severely exceeding payload/GVWR and rear GAWR that it could have used them, but those were very rare and were situations I shouldn't have been in to begin with. Definitely adding them to my 1500 though and I'm sure leaving them full would be more noticeable on that.

Air Lift is the only one I've seen with the internal jounce bumper option.

I'll probably run the shrader(s) to the license plate mounting holes. Easy access and no new holes needed. I added helper bags to my wife's Tahoe and T'd them together. I only used it for one trip towing, but didn't notice issues having them connected. I may try that again this time while being prepared to separate them if I notice any issues from cornering or weight transfer. Could even use a single fill port and a ball valve to isolate them once filled but that seems unnecessarily complex.

I've got a Viair compressor I've had sitting new in box for a decade. It fits perfect in the unused battery tray on the driver side of my truck. I think I'll make a quick-remove tray with handle to hold that and a 1/2 gallon air tank. Gotta check the current capacity of the hitch wiring, and if high enough I'll have it set up to plug into that for power at the rear of the truck. Yes, I realize I could just run an air hose from the tank permanently mounted in the engine compartment, but what fun is that? Having the compressor on hand will be nice for not having to leave bags full after arrival on long camping trips, filling tires, beach toys, etc.
