Ben,
You can have stuff in there but cause you'll be a hektik drift0r like myself they will be moving around and it could break (depending on what it is!)
If you need to bring stuff, theres a viewing "hut" which is under cover so you could leave it there, my mrs will be there so sh can keep an eye out, and plus we all good people!
Ive cleared everything out - last time I didnt and my tool box went everywhere in my boot
clutch seems fine!!!
lets just hope she's all good!!!!
