A solid month long mission may be difficult to carry out due to National Forest camping restrictions. Perhaps two 14 day missions with a minor relocation. Recently, I reviewed NFS policy for my area. For me, I am limited to 28 days per year of dispersed camping. The common day limit number in National Forests is 14 days at one campsite and then you relocate. The policies for relocation vary. The Idaho Panhandle National Forests should be individually checked. Idaho is a bit different. Marijuana is not legal and they do not allow public nudity. Where is the fun in that?
Colville National Forest is also 14 days at one campsite. I am sure that a forum member will chime in with a different opinion.
I work alone so that I am always outnumbered. I carry a lot of water for one person. I cook with propane so that I am already set up when campfires are banned.
In reviewing the 4 person mission with the F 350, I did not see water capacity listed in the early stage of planning. 4 persons ( and dogs ) for 28 days is over 100 gallons of drinking water. 4 stinky guys need to wash up so that is a huge amount of water. I can envision a small, enclosed utility trailer that will carry hundreds of gallons of water, propane / alcohol fuel supply for cooking / heating wash water, food and air tight bear proof containers to store garbage. You can't assume that burning garbage will be possible.
N E Washington would be cool. Bears, deer, cougars, moose, wolves and our cousins. We lost the last of the Mountain Cariboo when they were captured and kidnapped to Canada for a species rehab project.
