I do a fair bit of overseas work but not enough to qualify.
Your passport stamps can document how much time you spent out of the country but check with the IRS in regards to what qualifies as your official residence/domicile. You might be in the right but still get a nasty audit because you are outside of the norm.
Also, you need to check on how the online income will be reported. Typically, if it is for a job that occurs and is paid in the other country. If the online income shows up as US based income, it doesn't matter where your residence is.
A final thought: If you are boondocking mostly, I'm guessing there isn't a ton of income involved. If you are only making say $30k/yr, is it worth the hassle? After standard deduction, you may only be paying 10% on $6-8k. If you can claim business expenses, it might not even be that much. Is it easier and more foolproof to just file and pay the taxes?
