I've not been able to sell my Landy so am now looking at ways of incorporating it in to my window cleaning operation. As it's a short wheelbase the tank will not go in the back so I'm looking at a towed solution. Two choices as I see it: 1. A trailer with a tank fitted in to it which has the advantage of presumably giving me storage space for hoses etc. or 2. a bowser arrangement, which would probably look neater but would have to be adjusted to take filters etc. Any suggestions or experience of these ideas? I already have filters, ro, di, pump etc so don't need a ready made trailer system.
