Congrats on the X17Z. We bought one this year and have been on two trips so far and we absolutely love it. We keep a collapsable/popup type hamper in the shower as well for dirty clothes.
We travel with 4 people (2 adults and 2 kids ages 5 and 7). We each have a duffle bag for clothes. At night, we keep the bags on the couch or dinette seats. After we're up in the morning and changed for the day, our bags go on the foot of our bed and the girls bags go on the foot of their bed. During the day we're not on the tent ends, so keeping the clothes up there makes sense for us.
The X17Z isn't huge by any means, but it's the perfect size for us and has nearly all the amenities of the big trailers. We love it!
