Hi,
We too have a Powertouch, fitted to our Bailey Pageant S7 Provence. We opted for the power actuator, since I phoned them up and haggled a deal with them. Effectively, we didn't pay for the actuators.
The fitting service was great - they came to our storage site, and performed all the work on site. They use subcontractors, but the guy that came to us was very friendly / knowleagble / conscientious.
As for the movers themselves - wow! They are fantastic. We have to hitch the van onto the car on a fairly steep downward slope. This is a problem - trying to hold the van against the slope whilst manouvering the last inch or so. Not any more! The movers are so accurate, and start so 'softly' that you can literally move the van fractions of an inch forwards / backwards / clockwise / countre clockise. It will even turn 180 degrees in it's own length (ie, the near and offside wheels swap position exactly).
According to the guy that fitted it, it would move our van (1500KG MTPLM) up a 1:4 hill - I doubt our tow car would manage that! It climbs kerbs without any trouble.
As previously mentioned, they also come with a 5 year 'no quibble' warranty. When I was looking at which movers to go for, I posted a thread on here asking for advice. I had a number of responses praising their after care service.
HTH
Vince.
