I have.
But only as an "add on" when I took on Dan the Man before buying a bigger van. Now we use it for carrying gutter vac kit/tip runs and for camping holidays.
Anyone else?
So have I.
It got me started into wfp but I wasted a lot of money buying it.
I should have sold my Suzuki Carry van I had before going wfp and bought a bigger van right from the beginning.
It was one of Peter Fogwill's all in one package.
http://www.window-tools.com/window-cleaner-trailer-system.htmIt was open to the elements with 3 x 125 liter tanks running length ways. We didn't have controllers in those days so used 1/2" garden hose. Oval Vikan brushes with 3mm jets on ali Unger Teleplus poles. The leisure battery was mounted on the front drawbar and only last a year, probably due to being out in the elements.
I used the Suzuki to pull it and carried 4 extra 25 liter containers of water for ballast and extra water. 475 liters lasted me to around 2.30 to 3.00pm and then it was off home to process more water. The r/o was part of the system and I processed water directly into the barrels and tanks as I didn't have an ibc tank at the time.
The major downside was having to drive into and reverse back down cul de sacs, especially those on a hill. The trailer was much narrower than van and I could see the trailer in the mirrors which made reversing a pain.
The axles weren't designed for the weight and had to regularly replace hubs and bearings. The metal frame started rusting virtually from day one and at 4 years old I scrapped the trailer as it was rotten.
