auxilary air setup

i have a late 99 f 250 psd and recently got the firestone air bag kit for the rear, I have used them several times already and love them, and now i have the compressor kit, it is the lightest duty compressor they offer and I was wanting to set up a nozzle to air up a tire and i also have a set of air horns off a semi I was wanting to put on, my cousin said I will have to get an expansion tank for the horns because the compressor wont keep up, Im trying to engineer a setup that would work and im not sure what to do i feel like the control module is to deeply controlling the compressor for it to be easy but i was thinking going from the compressor to the expansion tank and then t for a air nozzle and t again for the horn and then go to the valve block for the bags with a valve between the 2nd t and valve block so i can get the pressure i need to air a tire, does anyone have any advice or done a similar set up that could help me? I have seen a few builds where guys put a large compressor in there tool box and ran it off the battery but I am not intrested in doing anything like that I was thinking about using a half gallon tank, this would be plenty for the horns and the air nozzle would get used very little. let me know what you guys think thanks

A half gallon tank is way to small! I run a viair 380c to power my Nathan k3la's with a 5 gallon tank. When that tank is full it'll air up a tire no problem. If its empty I'll have to wait about 4-6 minutes for it to fill up the 5 gallon tank. If you ran a half gallon tank that compressor couldn't keep up filling a big truck tire. View my gallery, I have pics of my tank, compressor, and train horn set up. I used my upfitters to control it, aux 1 is the horn trigger, aux 2 is my compressor on and off switch. Even though its on a pressure switch you still want to have the ability to turn it off and on I'd the pressure switch fails or if you just don't want it running everytime you drive the truck
