Im looking to get a air compressor to mount in my 73 K20. Mainly just to air up my tires, and probly the tires on my bro's truck. I want something that actually connects to the battery and not just the cig lighter. Also I searched in a 50 mile radius and cant find the $25 air compressor's I saw on here. I really dont want to spend $200-$300. I would love to find something in the $50-$100 but dont want to spend an hour airing up my tires.
