Great RV, we would rent this again. We added delivery and cleaning and everything was easy and timely. The unit was well kept and stocked with lots of gear including an outdoor rug, grill, towels, sheets, etc. You don't need to pack much.
Only note I can think of is if you plan to rent for a long time or bring a lot of stuff (food for more than a weekend, kids toys, etc.) then maybe let the owner know you'll need storage space. Because this RV is so well stocked with gear, there isn't a ton of empty space for storage.
I didn't take any pics, but the ones posted here were accurate.
