You shouldn't have any problems with the install, the garage lift will surely speed things up. I installed this about 3-4 months ago. Just jack up the frame and let the suspension droop, and stuff the air bags in the springs. Then route the air lines to your preferred spot.
I spent the majority of my time deciding and routing the air lines. This was the best improvement I have made so far. If you've ever hauled or towed anything that made you disappointed by the ride height when loaded, you can't go wrong for the price of these bags.
I just hauled 5k lbs of gravel on a 2300 lb trailer with the bags pumped up to 33 psi and it looked like the stock ride height. I leave the bags aired up to above 30psi all the time and the rear susp is a little stiff but I'm coming from a 3/4 ton so its no different really. With them aired up I get some axle hop at times if the potholes and my rate of acceleration are just right.
I thought about getting a level kit because i got 7/8" lift at the rear hitch with them aired up empty, but decided to leave it sit at stock height. I think a person that tows regularly with these bags could get away with a level kit though, without looking like the headlights are pointed at the sky.
