If you are just starting out a trolley in my opinion would be a nightmare, I did it, what happens when you first leaflet/canvass you will end up scattered customers two or three here and there, so with a trolley you will spend all day loading and unloading a trolley as well as securing it. Obviously guys like dazmond have established well compacted work and the trolley works for them, but for someone just starting and I talk from experience the van mount is quicker. I only lasted a few months before I stripped the trolley and added a tank in the van. and it was immediately faster and less hassle.
