Lots of paper plates and holders. Plastic everything...coffee cups, glasses, (real silverware is OK), etc,etc. You are camping...not going to a black tie dinner. Any heavy pots and pans go in a bottom drawer. Ponytail ties will keep opposing cupboard doors closed.Take out the glass plate from the microwave when traveling...dont ask how we know. Slowly but surely stock up the trailer with pots,pans, undies, socks, footware, shirts, pants, coats for all seasons. Leave them in the coach so you dont have to spend hours loading and unloading everytime your go camping. Then all you need to do is load food. Start the fridge a day or so before you leave. Get a bag of some kind to put dirty clothes in. When you get home...take the bag in...wash the clothes and put them back. Wal-Mart and internet is where we go looking for RV stuff. Make sure you have at least 30' of sewer hose, 30' fresh water hoses and a hose for the black tank flush only. Get a good water pressure regulator with a gauge and 5-6 GPM flow....no more than 50 PSI to the coach. Cosco has some good folding chairs with a cupholder/shelf. Plastic stacking blocks in a bag for leveling.
Don't buy every do-dad that you think is neat. As stated, keep a list of needed things and only buy WHAT YOU NEED....NOT EVERYTHING YOU SEE.
