We are weekend campers. Dishes are heavy duty plastic or thick paper/cardboard (Chinette (sp?) is great). Cups are plastic and/or steel mugs. Utensils are heavy duty plastic and stainless, which ones we use seemingly depends on our mood.
If things can't be put in cabinet with securely closing doors, we put them on the beds (obviously temporarily just during travel). Coffee maker and other items we wrap with beach towels and put them in a cabinet.
Also, don't forget about the oven! We put some pots and pans in the oven... and the microwave is good to use to store stuff. DON'T forget that stuff is in there!!
Just before we leave on a trip, I look around the camper. Anything loose is either secured or put on the beds. ANYTHING will move and/or fall to the floor if not secured, so keep that in mind while storing stuff.
On the other hand, sometimes we'll forget to put something away and nothing will happen - like a friends large ceramic coffee mug sitting on the kitchen counter the whole way home on rough roads. It barely seemed to move.
See you on the road!
