Gary, those are excellent points. I don't need every socket made, just a few basic ones. If I need a new one bad enough, I will buy it on the road. A pop riveter is a great idea too.
I do have the basic Ryobi battery drill/driver with a recip saw, and I was debating on taking them. Now it's a definite.
We are planning to full-time for at least a year, and we have considered the workamping option. I was thinking my tools might come in as useful while doing work. (I.e. build some steps, or a deck) but the workamping jobs seem to be scrubbing toilets, and greeting guests. Maybe I'm wrong. Maybe I will bring a weed whacked and tell 'em I'm a landscaper. ;D
