Alex, my work and round which is not a full-time occupation at present, is easily done with a trolley, and I dont find filling it a hassle although I would welcome something like a 35ltr container on it.

At times I do use a 60 mtr microbore hose off the trolley which gives excellent flow rates to 25ft ( havent tried anything higher as I dont have the need ) and its great for certain houses but I find pulling a trolley with me is a lot easier than hauling a hose then having to reel it in for 80% of my round. Also the obstacles I encountered with the hose are a pain in the neck- ornaments,garden pots etc - why do larger houses think they need so many urns and statues?
As it works for me I dont see the value in the extra expense of a van etc for my round as it is now. However I do see the long term value if the returns fill the right boxes. btw I work out of the back of a Pajero 4x4 - a Shogun in this country
keep up the good work down there
