Hello,
Here are pictures of my car unpacked and packed for my 20,000 mile trip. I was on the road for 90 days with my tent and the hospitality of hundreds of Corvette Enthusiasts.
It looks very neat and tidy, but once I was on the road, it was as messy as a kids room after play time.
I did not take a spare tire, I used the space to pack my tent and sleeping bag and stove.
