Nice Report all around, well done...
On my reasoned trip I also ....
A) used the space below my seat for a 3 Ring 1" binder with maps.
B) used the glove box for my digital camera and camcorder.
C) used the shelf behind the seats for a Roots Folding chair, my camera try-pot and an umbrella.
D) we also found the trunk space enough for a small suit case, rucksack, my daughters dowel bag and a very small cooler (holding about 8 small water bottles and ice). Good that my daughter only accompanied me for a section of the trip or I would have had to ship a cracked rear wheel by UPS
Oh and I discovered how to change my play list and artists on my radio when using the iPot (also always in place).
