My advice
Stay about 32'
Buy the nicest gas one you can afford - used but nice
Invest in solar to recharge
LED lights
Get a good list of boondocking or free campsites
Look into work kamping or camp hosting, as stated
Check out county and town parks- sometimes only 10-20 bucks a night
Walmart once in a while for a night here and there
Cook easy, simple meals - double what you need and freezer remaining
Take advantage of the free days at the museums and local talent for entertainment
Stay away from the casinos
Keep a journal of your fun - or not-so-fun things that happen
Breathe and enjoy
