New Trailer traveler - light weight, single

I'll agree with Grit dog and suggest you purchase a used or rent to see if this will work for you without a big expenditure. Lots of books also available on low or no cost camping. As someone else pointed out you will have no A/C without electricity. You might be able to add larger tanks if you have the room as well. Solar could keep the battery charged when boondocking without power. Good luck with whatever you decide.
