and that's it, the complete list of absolutly everything in my motorhome. I have no food on board as I eat at the college caffeteria (included in the cost of my tuition) and at Subway. Except for the things which I noted as not having used, I use everything I brought with me.
And yes, that does mean that I do not have either a phone or a tv, nope they are not on the list because I do not have them.
Yes, I do, stick pink flamingos in the ground around my motorhome when I park. They match the green metal flake.
Yeah, like everyone else said: just take what you use. Figure out what you use every day, and bring only that. It's all you need. Everything on board, I use. Everything I don't use, did not come with me. The reason I have 6 each of dinner sets, is because, in case I have guests over, say for Christmas dinner, I'll have something for them to eat on.
Also, don't change who you are and start dressing different because you moved into an RV. Jeans, t-shirts, camp gear? Nope, zip, nadda. Don't wear them, don't use them, never did, never well. Sequined ball gowns and mink coats? Yeah, wear them every day. When you see me in public, you will know you have crossed my path. I do take my Liberace obsession to the extreme.
But than again, as you might have guessed from the cards, spirit boards, and crystal balls, I'm also what most would call a "Gypsy Fortune Teller" and by culture, this is just the normal way Travellers dress anyways. So, yeah, wear what you already wear, don't go all jeans and ts because you live in an RV, if that's not what you wore before living in an RV.
