This doesn't necessarily apply strictly to campers, but I value the opinion of most folks here so figured this was worth a shot. I've been toying around with the idea of buying an air tank and compressor for the garage. I do enough tinkering around to warrant it, and I've been looking for a few years. My primary uses would be: 1. Keeping tires on all vehicles properly inflated 2. Blowing off my workbench 3. Likely purchasing a small number of air powered tools (for instance, something that would allow me to properly torque the lugs on all vehicles, likely a finish-nailer, rivet-gun, etc) for light-duty use 4. MAYBE toying around with a paint gun and related items My question is, what should I be looking for. I've done a bunch of reading and I know there are a million different things to take into account (volume of the tank, power of the motor (HP), CFM, etc) - I'm aware that those things exist but I'm not sure how much HP I need to fit my needs, for example. Any opinions welcome!
