Seriously hope this doesn't come off like a smart ass. You have to have the skills/knowledge to fix what is broke. Or the pockets to pay to have it picked up.
Seriously though, if you're building a daily, plan out your valve, tank and compressor placement for fairly easy access. Carry a few spare parts with you. Examples, extra airline, a few splice PTC fittings. And if you're going on a long trip maybe even an extra bag and a short piece of airline with a Schrader valve connected to it . And of course a few tools to get the job done, a jack and what ever blocking it takes to get it under the vehicle.
And then if you're paying someone to do the job for you. And you have no idea what makes it work. Plan on paying to have it picked up and fixed.
The variables of things that can go wrong is limitless. And something inevitably will happen eventually.
