yep!50L TROLLEY does me fine.30m of extension hose i dont have to move the trolley as often.less of a trip hazard and im not tied to the van all day!!
i also leave it in the van as a mini van mount for the odd stand alone job.
most of the time i take trolley out in the morning and put it back in the van at the end of the day my round is that compact!!
some time is spent changing barrels but weighing it up with 100m of hose and the extra risk of trip hazard/getting stuck on car tyres/wheelie bins/bad access then its fine for me for now!
also in winter my system will be nice and warm in the flat so no risk of freezing and damaging pumps etc overnight.
i can unload everything out of the van if i need to use the van for anything else(taking stuff down to the tip or going to ikea!!)
a lot of advantages for me with a trolley.
