Make a couple shake down runs at a near by camp ground. You can either run to the store or head back home to grab something. After a couple of trips you'll have a good idea of what you want.
I end up tailoring my camper to the trip now. If were leaving for a week or so i brink everything and the kitchen sink. if its a quick weekend up north where we wont be doing much hanging out at the camper then i pack light. Clothes, coffee provisions and maybe breakfast stuff. Might even want to toss a pack of hotdogs and smore stuff in the fridge. on long trips i pack everything. I even go through my tool box in the garage. bring things i don't need.
Some trips are for relaxing at the camp ground and some trips with the camper were just using it as a hotel room on wheels.
think about your trip as your packing. Grab things from the house. If you keep finding yourself saying "ah ****, that pot is in the camper" buy another next time you go out. If you find yourself constantly annoyed by something you never use and its always in the way at the camp sited then take it out. Alot of items i thought id need get tossed.
