As the title says, is the factory (2009) towball Alko proof? I was told it was however I am not convinced. It is the swan neck fixed/permanent towbar, not detachable. eh tu?

Statement - Alkos and Swan necks are compatible.
The problem with ALKO's occurs when trying to use a Alko hitch and a fixed two bolt flanged towball. The problem is that most 'original design flanged towballs' had the ball in close proximity to the bolting flange. in certain instances an Alko hitch can clout the flange/bolts etc and cause damage.
Alko flanged towballs have a longer neck to spacer the ball further out to avoid such collision of components.
Any Swan Neck whether fixed or detachable has the ball well clear of any obstructions so there are no compatability problems.
Just remember to use a towball free of paint and grease when using a Caravan with an Alko friction hitch; and to grease the ball if towing any camping or car trailer etc that doesn't have a friction hitch.
Best advice is to carry in the boot an aerosol can of degreaser and clean rags for the Alko towing regime and a small tub of grease to allow standard old style hitch towing regime so all eventualities are covered.

Thanks, pretty much what I originally thought however the caravan dealer I was at on Sunday were suggeesting I needed a new towball. Now to order that caravan! eh tu?

My caravan stealer actually changed my existing tow ball for the compatible one with long neck (I know a bird with one as well but that is another story) and a slightly longer horizontal part with the 2 fixing holes.
He actualy gave me back my original ball which gets used with non Alko hitches.
