I've just ordered a Bailey Cartegena. As it's a twin axle I want an AWD mover. I've never had any trouble with Powertouch movers so have ordered one of these for DIY fitting. Bailey say that they have altered the spare wheel location (backwards) so the AWD will fit. Powertouch say it won't fit without removing the spare wheel and carrier. Who is right? Has anyone out there fitted a Powrtouch AWD mover to either an S2 Barcelona or a Cartegena? If so, was it necessary to remove the spare wheel and carrier?
Powrtouch AWD Mover

I have a S1 Barcelona.I have a powrtouch mover on the front wheels. I used the same model on my previous van, a Compass Rallye Twin axle (1900 Gross weight). In both cases the mover does the job. Do you need AWD, Paul?
Thanks Ronald, I need to do some pretty tight moving so the dealer has recommended the AWD. However, just had an email from Bailey confirming that the AWD will fit. They have also contacted PowrTouch who have now confirmed that the AWD will fit so all is well!
Hi.
If you recall how much harder it is to turn a TA compared to an SA by hand you can begin to understand that a mover designed for an SA is not reccommended for a TA. Using an SA mover on a TA will be putting a much greater load on the motors and bracket that they were designed for. It will also cause teh motors to draw far more current than they should, which is not god for the motors, or the control relays.It may also put more strain on the battery which may harm it.
The mover designers have gone to considerable lengths to engineer TA movers, They have had to incorporate all sorts of tricks to over come the vastly greater loads and resistances to turning TA present.
For greater certanty of operation stick with the products that are designed for the job, Otherwise if a failure occurs, the manufacture can legitimatly point to the fact the product was installed contrary to its instructions, and thus warrantyor guarantees will be void.

You've lost me John in what you are trying to say here. I have a Powrtouch Heavy Duty designed for TAs upto circa 2000kgs but with motors only on one axle. Granted it can't pirouette like a SA but it will move this heavy bulk up a 1:4 slope and it has a "pulsing" mechanism that will help with turning. There is of course a trade off with a 4 motor unit on your MTPLM that may reduce your useable payload. Does he really need 4 motors??Prof John L said:
The salesman at the dealership that I went to explained all about "pulsing" movers for twin axles versus AWD. He doesn't deal in Powrtouch movers so he wasn't trying to "up" his commission but his view was that it was far better to go for the AWD version. I have some fairly tight turns to do and his view was that the single axle mover wasn't suitable.
Hello Dusty,
I'm sorry you didn't understand my post. Let me try and clarify:- When I refered to SA and TA I was refering to the caravan not the mover. I was not refering specifically to the numbers of motors a mover has.
Movers designs will fall into one of three categories
Two motors designed for a SA caravans
Four motors designed for a TA caravans
Two motors designed for a TA caravans
I am aware of a development project that tried to use a heavey duty mover designed for a singale axle caravan fitted to a TA. The turning performance was very poor and there were motor and control failures resulting from the excess loads.
At the time various techniques were tried such as pulsing which seemed to be reliable but it still lagged behind having a four motor solution with quite sophisticated control gear.
So if your mover only has two motors and was designed for a TA then thats fine, but its definately risky trying to fit a mover designed for only an SA on a TA.

Hi John,
Thanks for that.
Six years ago our dealer persuaded us to go for the Powrtouch heavy duty, two motors on our TA.
This was to preserve our usable payload and avoid the extra expense of relocating the spare wheel, waste water outlets and jacking points. The latter could be problematic.
Powrtouch say their HD model is specific to TAs. Granted it doesn't spin on a sixpence but with it's pulsing action on the turn performs reasonably well, allowing for the tradeoffs.
