I like locations where I can get a good view of the surrounding area (excellent vantage point of incoming/outgoing traffic) and an easy escape route in case of possible problems. Its best to set up a tent only if there's a good place to hide it from choppers who may see that shit easily and recognize the plants after seeing your tent. Set up your operation not far from a water source for your operation.
When it comes to soil - I think that its overrated to bring bags and bags of soil with you. I use the cheapest soil option possible and get great results. Its all about how you take care of your ladies, i.e. nutrients and maintenance. Blend good soil with native medium 50/50 and save on bringing too much heavy shit with ya. And besides, the ladies love sandy soils. Having a pair of really good binoculars helps with monitoring of your area. If you have portable power, you can even set up a 1000 feet range motion detector system if there's a local road nearby and you can get a warning of incoming traffic.
Its very possible to live with your operation for 3-4 months of the season. Buy a good water filter and dried food packs (the ones where you just add water + heat) that are good for 20 years.
I know someone who goes to British Columbia (province in Canada) every summer to do this very same ultra-remote guerrilla operation. I've never done it because I don't have a truck, just a car! He invests $3000-$4000 in seeds, nutrients, food and equipment and easily makes 20-30 times that back. With remote operations you can do as many plants as your local water source can allow to support. We don't have state lines and road checkpoints here, so you can literally drive your crop in a truck across most of the country without getting stopped once
