Some of this may seem a little remedial, but you'll see how important it is once you get on the road.
Packing for an RV trip is a lot like packing for any trip except you're going to want a few more items that you normally wouldn't pack if you were going to hawaii on a cruise.
The advantage to being on the road is that you can always stop at a grocery store to buy these items.
Use the check list below and you'll be glad you did...
