As has been mentioned previously, you can use whatever you like! I have Blue Danube china and sterling silver flatware (thanks Mom!). We have crystal decanters for our liquor and very nice wine glasses 'cause that's what the DW likes. We use cloth napkins (save the Planet) and and have cooking gear from Pyrex to cast iron. We have what we need and we could really not give 2 spits what anyone else has or does.
We have silicon sheets between some of the fragile stuff but there are foam and other separators available. A dish towel would generally work just as well. Travel with what you like and what makes you happy. We are not backpack camping so whatever you have room for is just fine! Weight? Really? You think your cookware is going to put your RV overweight? NOT!
