I agree with Jocko.
On two separate occasions I have carried some garden materials in the Jazz. I loaded it between the front and rear seats ( god bless Honda's magic seats) and some in the boot. One suggestion, if you have the split boot floor with it's load restriction. I cut a piece of ply and put the boot floor in it's up position and laid the ply across the spare wheel.
I found the Jazz to behave extremely well albiet a bit lower.
Good camping and hope the weather is kind.
