Congrats on your new Berkshire and welcome to the FORUMS!! Hope you have many fun, memorable, and trouble free trips with it!!
Do you have a washer/dryer combo, separate washer and dryer or neither? If you have the cobo like we have, I put some shelves above the combo and we store extra towels there. As far as in the bathroom goes, we got an over the door hanger (InterDesign® York Lyra Over-the-Door 5-Hook Rack - BedBathandBeyond.com
) that we hook onto the decorative wall hanging that FR puts in the bathroom. Works very well. We also put a couple of 3M Command hooks onto the frame of the shower by the walls. Works out well.
