no way in a million years would i use that van, it wont be secure in any way whatsover, not just that i bet the set up leaks everywhere, it looks like some 2 year old has put it together. Find out where he lives and go canvass his area cos i bet he does a crap job 
Why would he do a crap job just because his setup doesnt look professionally installed? I know a few window cleaners that have fitted systmes their selves, may not look very good from the inside, but they do a good job.
its idiots like this that cost 'proper' wfp people work, i recently canvassed an estate and they all hate wfp, simple reason was that the muppets that went round there never new how to use it, they left windows rotten, never cleaned frames and they poured the water through all of the vents. im sick of cowboys costing 'real' wc's work 
rant over, well for now anyway
Again, why would he be a cowboy just because his van doesnt meet your standards?
exactly
oh look he doesnt have a professionally installed system, he must be a cowboy
the facts are, he could be using a old beer towel and using a ladder made of some 3 X 2 " timber and still be getting clean windows ( just as clean as a professional system infact )
it might not be safe, but i guess the owner knows the score, when he sells it, most would look at the system and think, i might make that safer by doing this and that ( its not rocket science )
i await the " i bet they didnt go to window cleaning school either " and " my system was crash tested in a completly different van, but hey its still crash tested " and " my system means i get commercail contracts all over the world and they even fly me first class " and , oh i cannot be bothered to continue doen the route
