As others have said, it depends on your work. I have a very compact round, most of it on modern estates. The problen I find is that on modern estates the houses are packed so close together, parking is the big problem. with so many two car families, with only room for one on the drive, and the other parked in the road. It's swings and roudabouts, you either have to go back to your van to get fresh containers, or back to the van to move it to the next house. With a 50 ltr trolley you can do a few houses. Or again as others have said, you can run a van mount with your trolley if you want to. for me it has to be a trolley. Dai
