I agree with splitting duty…
I have a CKMA12 mounted under hood by a bracket to the left of the brake booster (easier access than the tray). After using it one time to fill up one of my 33X12 tires and seeing how hot it and the air hose got I decided to never use it for tire duty again. It also was slow.
I carry one of these behind the drivers seat for tire duty, it durable, fast, and doesn’t get hot. Also love that it’s in a ammo can for styling and also because it keeps water a dirt out of it. https://specialopstools.com/products/air-armor-m240-12v-off-road-air-compressor
