I just have some short tips. When you are travelling in Sweden: avoid the 2+1 roads. They are narrow and big trucks comes very close. It's quite easy to get away from them but the trip can be a bit longer. I haven't travelled too much in west Sweden so I don't know the roads very well. The other tip is to google "Allemansrätten". Simplified it means you can overnight almost anywhere in the nature for one night and then move on, as long as you don't damage it.
