With your limited income, a truck and trailer or 5th wheel would be the best choice. A motorized RV can be very expensive. Purchase something used. But before you purchase anything, sit down with Excel and develop a budget and see what is possible. Your fuel costs will depend on how often you move. Your site costs will depend on where you stay. Your propane and electric costs will depend on the outside temperature. Make sure you have money for insurance, maintenance, health care, food, etc. No one can answer your question because there are too many unknowns.
