With the Affordable Healthcare act, you get a subsidy on both your premium and your deductible if you make less than 200% of the federal poverty level which would be around $31,000 for a couple. If you are talking true workamping, you will probably have no problem making less than that. Another poster was correct, use your estimated 2015 income, not what you made in 2014.
If you earn more than 200% but less than 400% you will still get premium subsidies, but the subsidies for the deductible go away. Therefore, it might be advantageous to limit your income if you are going to be right around that threshold amount. The deductible amount soars when you cross that limit. If you are comparing plans subsidized plans, always check the silver plans, since that is what the coverage is benchmarked against and often the subsidized silvers have lower premiums and deductibles than plans with higher or lower color choices. (It's the government, it doesn't need to make sense)
Something else to consider/be aware of, is if you make less than 100% of the poverty level, or are in a state that expanded the Medicaid threshold, you will have to enroll in Medicaid and not have private insurance available for a discounted amount. That might limit your choices of doctors and might have severe impacts on your future estate since Medicaid payments are subject to clawbacks from your estate. If you plan on working in a state other than the state you reside in for insurance purposes, be sure to have a plan with nationwide networks, generally a PPO plan. Be sure to doublecheck, because after February 15th, you can't change until November.
A bigger question to you is WHY would you want to fulltime workamp at your age? If it is traditional workamping (low wages, labor for site, etc) you are going to effect your career track and retirement severely. In your 40s you are very hirable, in your 50s, not so much. Your 40s and 50s should be your peak earning years. This is when you should be investing for retirement. This is the high earning quarters that determine your Social Security benefits. If you are looking to bop around for a year or two, maybe. If you quitting the traditional workforce and want to make a life out of working and traveling, resign yourself to doing it until you die, because you won't have enough retirement income to fully retire when cleaning restrooms and checking guests into RV parks isn't quite the adventure at 65 that it was at 45.
