Judy, I wasn't very smart about packing given that it took several trips to get things into the motel rooms! I made some changes along the way. There is a compartment behind each seat so electronics could be locked there. The SS rain cover and small cooler took up the passenger floor space. A Rubbermaid type bin (bought on the trip) took up the passenger seat. Luckily, motels often have guest laundries these days! There are many luggage configurations out there - mostly mounted to the roll bars. If I were doing this often, I'd figure something else out.
I'm already considering a couple SS only trips to rallies next year.
