That's what I was thinking... Car and trailer pulls you down to local places and too cumbersome. A much better option is just fly to some place, rent something for 1+ month (or even a hostel if you want to go really cheap) and live there like a local. Staying in one place for at least a month (ideally 3-4 months) is very important so you don't have urge to checkout everything in short period and get distracted from the work. The idea is to be local and live like local.

For computer setup, I would highly recommend 17" laptop + portable monitor (for example, https://www.amazon.com/UPERFECT-Resolution-2560x1600-Raspber...). I also get beefy laptop with GPU with 4k display. I usually add iPad as my 3rd display for music or whatever.
