At the sake of offending any of the
Butler clients, this guy is in the UK. Correct me if I am wrong, but
Butler units only suits certain types of USA based vans, of which they don't have in the UK (or here in Australia for that matter).
That is why we (and him) will generally have to rely on a good slide in Truckmount. Another thing we have in common over here with cleaners in the UK, is that apart from the Spinters etc, the standard sized vans are much smaller than what you guys in the USA are used too. So a small but powerful slide in would no doubt be on the short list.
As Bill suggested, go an talk to the guys from
Prochem of Europe, as they will have all the answers to what you are looking for, and have assisted many cleaners before and can highlight any potential issues you may have yet to consider.
Talking of small vans - and this is small even by our standards, we had a client the other week that asked for us to install a truckmount into his little suzuki vehicle.
