So far so good!
-As a clarification, I previously had my truck stored at a vehicle storage facility on a monthly basis, that very kindly let me work on the truck while at the site. Unfortunately the site had no water or power; I ended up buying an external battery bank(that also has an air compressor large enough for my truck tires, and a large jumpstarter), so I could use a drill to finish putting up the wall studs. I ended up sawing them by hand (saw used too many amps), hammered them in, and screwed through the metal into the studs from the outside. This worked amazingly. I was under a hard time schedule to get a lot done before it had to be moved, and my generator had to be grounded with a stake outside without rain or snow or damp soil. And it must have rained for a month. The bank was useful for the drill and air compressor, but I haven't used it much since. [Edit 12/12/18: Now that winter has arrived and I can't run an extension cord, this battery bank has become very helpful.]
If you're considering doing a project like this, but can't park it where you live, consider a vehicle storage place! Someplace that stores RVs, Semi-trailers, and the like is perfect for what you need. (And I bet you'd meet a lot of kind like-minded people like I did.) If you choose this route, I'd recommend a generator instead of a battery bank.
If you get one like this Yamaha ----> Yamaha EF2000iSv2 2000 Watt Inverter Generator, not only would it be more than enough power for your tools but a lot of people use this as their main battery supply for their home. [I'm going for a full solar setup and i've never used this generator, but this is the most commonly referred to generator for RVers and self-converters. The high price tag upfront is less than a solar setup - I'll be spending somewhere around $2500-$3000 for my full battery bank, with the same wattage capacity. But you'd have to buy gas for a generator which adds up over time, and they can be loud.] I thought I'd just add this information in before we get to the framing.
