Well Robo,
You have three issues to deal with as I see it.
1 - You feel you have to get out of the state.
2 - You are hoping to use an affordable mobile residence to make this feasible.
3 - You need a mobile residence that will work were jobs are.
As to line one: I can't argue this at all. Go Some Place else. Even though Michigan is now a "Right to Work" state, that will take another three years (at least) to have an effect. We are now retired and the house we have lived in for over 20 years is just now getting up to what we paid for it.
About line two: Living in an RV is more expensive than you might believe. You need to be someplace that you can access electric power, potable water and a sewer dump. This typically means a real RV park. These can be more "reasonable" at a monthly rate, but they still are not free. 4~500$ per month is pretty common and may not include the electric cost. Southern is usually lower. Then residence issues kick in. Check out the costs before you uproot.
More about line three: Your mobile residence can be a trailer (what can your truck tow?) or a motorhome. Both have some of the same problems.
The Cheap ones aren't free and a Free one isn't cheap.
A - If anything you look at shows signs of water damage and it is not an all metal unit, walk away. Repair is complex and expensive. If it has square corners on the roof, it is stick and staple. If the wood rots (this can happen fast) is will loose integrity and it is toast.
B - Very few are insulated enough to be "4-Season". This means if you go to North Dakota (Unemployment is 3%) you will either spend a fortune heating or freeze you butt right off.
C - If it has not been run at least 1000 miles in the last year, be cautious. Sitting still is not good for running gear.
Michigan did take it in the ear when two of three were forced into bankruptcy. The state is coming back and the election will determine how fast. I got cut loose in the Chrysler purge of 2001, I was a highly respected but old member of the automotive development community. I did a lot of work on pleasure boats before the depression, but that is all gone now. Over two thousand uniquely prepared resumes and cover letters yielded about a dozen interviews over 10 years. So, I worked little low income jobs until I could hook SS. My investments for retirement were "redistributed", so any possibility of comfortable life is squashed.
What ever you choose to do, I do wish you and your family the very best.
Matt
