I haven't been to storage yet, but thought I'd start a list of items here that I can bring to Q - I'll add to the list and try to get some photos

Adding: slinky to hold sewer hose off the ground
Pretty sure there are various small wastebaskets and 'dish pans' for storage
Green Machine carpet cleaner
Plastic yellow leveler blocks
Small pine table
