When are you going and what area are you traveling?
Im heading cross country late June. PM me if you want.
There are sites like Camp free in BC (directions to hydro dams, hiking trial heads etc in that province
In the US, I look for green spaces on a map, but do not camp on indian territory
I carry a two man tent, and keep all my gear inside with me.
I also carry a bivvy sack, I have slept in the ground next to my bike in truck stops and behind tourism booth if I have pushed it too long. (Bivvy sack set up and packed again in minutes)
gravel side roads, graveyards, power line easements all make good spots if you are looking for free.
Here is a sight with tips for free (otherwise just head to state park campgrounds etc)
