For batteries, I would be looking long and hard at GC26V golf cart batteries. It is the cheapest, more durable solution for storage. Check Sam's Club or Costco. I would also recommend a couple of 120-140W modules with a PMW controller. This type of setup is for a boondocker that doesn't use a lot of high-power electrical devices. Solar blvd is a good reseller, I bought my module and some other gear from them. Their customer service is pretty good, also. I needed a part from them and they overnighted it to me at no cost. Picking up the modules at Norco will save you $100+.
When you get the toy hauler and start to assemble your studio gear, you can take the first installation along with you and upgrade a bit for more power.
