Right now I'm leaning towards setting up my 1998 with 1999 tall coils, OEM shocks and wireless controlled airbags in the back coils- that way I can add a little air in the back when I have more weight in the back while preserving the ride...
Or plumb out two schrader valves to an accessible spot and use a small hand pump (bike shock pump or similar) to air them up. Saves a couple of pennies.
