Everything can be portable like the contractors with their work trailers. Get something like a 16' trailer, and fit it up for your bench, tool boxes, air compressors, and parts bins. If you look (google contractor trailers (images), you will find some really neat shops built into trailers, complete with lighting, heat/air, etc. Yes, you would need to downsize your stuff, and Yes, your working on vehicles outside, and Yes, life would be different from having a dedicated equipped inside shop. But think about the contractors, and how they actually "bring the shop to the job" instead of vice versa. Some of these trailers even have sinks and microwaves like RV's do. For me, I like working outside even though I do have a full shop. What I am liking as I get older is the idea of downsizing everything. Ask yourself how much junk you keep around that never gets used? I was once storing junk in a garage, and letting my new car sit out in the weather. That was really dumb on my part. Now if your running a neighborhood garage, or your building project cars every day, this would not be a good solution. But for the mobile guy who is going to be relocating "often" and the new place would allow for parking a trailer of say 16 feet, it is a good solution. LOL, why not just sell your house and buy a Winnebeago to live in and trailer to keep your workshop in? If you get tired of where you are, just pick up and leave!
