I tried to do a search because surely someone has asked this, but I didn't find anything. We bought a 2017 Bullet 247BHSWE (our first RV). We don't get it till next Friday, but of course I'm alread...
We use standard full/double sheets on the bunks. We got sheet corner straps (sold at wal mart) that have clamps on each end and about a 10" piece of elastic. They take up the extra slack on the cut corner.
We like to cook - so out kitchen is stocked - couple cast iron pans, non-stick pan. Large pot, small pot, couple baking sheets, and a cast iron griddle that fits on my camper grill.
