Sorry I took so long to reply, been busy busy busy, but not with astronomy unfortunately. Here is a pic of my gardenn cart you requested. I did want to be able to put the box I have all my eyepieces into it too, but it all a bit to big, and with the tripod leaning the way it does, it wasn't going to happen.
Anyway, hope this gives you an idea of what you can do, its simple and it means you don't have to carry the whole lot on your shoulders.
