Its alright doing contortionist routines Shaun, if you thin enough to get in to do the contortioning :
Thats one reason I like the Prowler, it can be taken out of the van easily (ramps) to get at components.
The way mine is mounted with the 400 litre water tank behind the bulkhead, if I take that out, then wheel the Prowler about a foot nearer the side door, I can get all around it to do a lot of work. Out with it for major stuff would make it easier, but ut can easily be swung round 90 degree so it in line with the lenght of the vehicle so you have cover from the rain and the sun still..
Its better then trying to find someone with a fork lift - and if you find someone - where do they put the unit when its lifted out..... its on their property. You better with it being at yours.
Answering Heritagecleaning question about where does the sucked up water go to.
You get 100' of extra suction hose for this (different colour). You can run it to a kitchen/bathroom water drain on the out side of the house.
Maybe easy access to a sewer drain so straight into that.
Can always modify a wheelie bin to collect it if drains are not handy. At end of job wheel it to a dirty water drain.
Or like I did yesterday, run the hose into a hedgerow or something similar.
