I have not seen a water pressure regulator mentioned.
I use to attach the water hose to the post, then the pressure regulator and then the filter. Saw my hose double in diameter. Now, it's the pressure regulator, filter and finally the hose. And we have two 25 footers.
IMO you absolutely need to bring at least the bare minimum tools to change a tire. Breaker bar, socket, jack (your AS won't have one onboard), torque wrench, and a reflective vest so traffic can see you. I would also recommend some sort of portable air compressor. And don't forget a headlamp! I use mine frequently.
