Hi, I've just started on an RV-9 and similarly I spend a lot of time working away. I'm using the time I spend travelling to do research, study plans & instructions, and just generally prepare, so when I get home again I can get stuck in. Unfortunately a lot of the processes are noisy as others have mentioned, but with a bit of thought & planning you can have a few quiet things to get on with (like deburring or fluting, hand sanding, soldering / crimping). I've thought about taking parts away with me, but again as already mentioned the potential damage or not having the right tool is going to make that a bit hard to implement.
However you decide to proceed, have fun (it is truly the best thing to be doing!), and you'll find all sorts of ways to stay productive.
