Cant say much that hasn't been said...
Your RV need (hoses, cords, blocks, etc)...
The rest is up to you. When me and my wife first got ours we took it out on its maiden voyage with minimal stuff. We had the basics, paper plates, plastic utensils. Our bedding was just a few blankets we had laying around the house. While on that trip we made a list of things we need to buy specifically for the camper. When we got home we hit up walmart. Got some cheap-ish plastic plates, a set of silverware (also cheap) a set of dishrags/dishtowels that matched the camper, a set of bath towels to keep in the camper, and alot of little knicknacks. I believe we spent under $100 and now the camper is equipped for a weekend WITHOUT dragging a bunch of stuff from the house with.
Also, Goodwill is awesome for camping stuff. We got a Comforter, BRAND NEW, still sealed in the zipper bag that matches our camper for like $15, also some other brand new blankets that stay in the camper and who cares if they get ruined or dirty. Goodwill is always hit or miss though, some days you find usefull stuff, other days you find nothing.
Good luck in your quest for stuff!!!!
