I'm not sure I'm clear on where these tools are for? Are you talking about what you should carry with you on the road or what you have at home? "Air" tools threw me off, if you're carrying air tools on the road with you I'm impressed!
It obviously also depends on what you do, or what you're willing to do. Carrying a ton of tools in your RV but you'd rather not lay on your back on the side of the freeway fixing something doesn't really make sense. Carry what you're comfortable using vs. calling for help or taking it in somewhere. I carry a lot of tools on the road, but I'm also ok with having to change a leaking exhaust manifold gasket in a grocery store parking lot if I had to. (been there-done that)
Let us know exactly what you're doing and we can give better advice. Here's my range of tools... (lol. I have been a mechanic for a living since I was 13.) First shots are a couple of my shop at home and last shots are what I carry in our Vegas. Look closely at what's in the drawers of the Vegas tool box, you might see something you should be carrying but aren't. Again, things like a tire plug kit are stupid to carry if you'd rather just call or get a tow, which is perfectly fine btw.
