1. Tension bars for the refrigerator to keep stuff from falling over and moving around.
2. Small baskets or plastic bins to also keep stuff from moving around in cabinets and cubbies.
3. Multi-purpose lighter with the metal wand for lighting camp fires, gas grills or oven in camper.
4. Stuff to do on rainy days when you might be stuck inside your camper, i.e. cards, puzzles, crosswords, board games or whatever else floats your boat.
5. Big cooler in case you have any problems with electricity or refrigerator.
6. Some kind of mattress topper because most RV mattresses are super uncomfortable.
7. One of those big camping mats, door mat, or both so you don't track in a ton of dirt or gravel into your new rig. You'd be surprised just how much stuff gets tracked in even in 1 day when you are on a site that is something other than grass.
8. Tablecloth that will fit a picnic table and some clamps to hold it on (in case it is windy). We've discovered that some picnic tables can be pretty gross, even if the campground is nice.
9. Enough camping chairs for everyone who will be camping with you, just in case there is no picnic table. That way you'll have a place to sit outside and eat and of course for sitting around a campfire.
10. This one isn't a necessity but we use them on pretty much every trip. Smores sticks! My kids love having their smores, but I'm not a fan of using random sticks. So, I found something similar to this. I have a store near me that sells them in a pack of 10 for $1.00 but I'm posting this link so you can see what I'm talking about. http://www.amazon.com/MalloMe-Marshm...hmallow+sticks
