Hi Vince,
I'm carrying all the WSCB banners, my 10x15 tent, various check-in supplies, PA system/speakers, jacks/tools, and luggage for 2 couples, so I'm pretty well tapped out on space and probably looking for extra space myself. Last year I was stacked to the roof and on top with more to carry this year. Keep checking around... If I did not have to bring all this stuff up there, my Cobra trunk would be my suitcase for two.
Good Luck!
