The higher number of separate runs you have the higher chance of leaks.
I don't have a separate compressor on my rig but do have a connector for hose if needed. It is located in the front in the event I have to be towed. It can be used to inflate tires (marginally since the governor doesn't keep tanks much above 110 psi). I also carry a smaller compressor that I can use but I have to jump it out to get higher pressure.
I looked at the system, looks good.
Good Luck and let us know how the install went.
