I used to use the front one for holding my XPower stool in place (it fits in there very nicely) and the back one used to gold my MG and XPower flags when they were rolled up

I have a first aid kit strapped in and a roll of paper.

Bottle of water for washers etc in mine..

Nowt in mine but i have added another strap around the back seat stay to stop my trolley jack and a big box of bits and pieces flying about. :)
