I have a Pure Freedom system fitted. I was always used to a side door 'pull out'
They fitted me outside ports to the rear (standard I think? )
In my opinion, much better - I can now work both sides of the van, I can angle the hose reel to suit.
One way terrace streets are now so much better.
I can lock the van without fear - the only thing that could get nicked, is my fairly expensive hose reel - but that's better than any poles/ladders Etc.. 🤞
