Just picked up a 450-RVS on sale and want to make it an onboard system but where?

Truck?

Mount the compressor in the truck and have quick connect amidships on both sides to use a short air line to reach the front and rear tires. Would need a much longer hose to get to the trailer wheels.

Trailer?

Mount the compressor and pipe air to the wheels on both sides, use short hose to air the tires. Would need a longer hose to get to the truck.

I know I have way too much time on my hands but I don't want to have a portable compressor as it inevitably got buried somewhere when you need to use it and I don't want 30' of hose to drag around.
