The fitting of a mover under a double-axle caravan can be an interesting challenge, but with a number of caravans it becomes a job for specialists. Not every mover can be fitted, because there are limitations to what actually, physically fits. Not all manufacturers supply a wide variety of mounting and clamp materials for an optimal fitting.
A double-axle caravan does not maneuver as well as a single-axle one. This makes sense because it is more difficult to make a turn with four wheels. We strongly discourage the fitting of a single-axle mover on a double-axle caravan, simply because it is not allowed and not covered by warranty.
2WD or 4WD
There are two kinds of double-axle movers, one variant with 2 engines (2WD) and a variant with 4 engines (4WD). With a 2WD it takes a while to make a turn. With a Truma it takes 1-2 minutes to make a 90 degree turn and with a Reich it takes 4 minutes. After all, only two wheels are powered. In our opinion, this is a good solution if you only need assistance with maneuvering with a load approximately up to 2200 kg. The 4WD steering is much more comfortable and powerful and turns faster as well.
We recommend our Optima Battery Complete Set 2 with a 2WD type of mover. The advantage is that when used in combination with our Optima Battery Complete Set 2 the weight is about 55kg. And, of course, the total price is less than a 4WD mover.
The 4WD movers can make a complete 360 degrees rotation (almost) on the spot. We recommend our Optima Battery Complete Set 3 (or 4) for this type of mover.

Fitting a mover to a twin axle caravan is not always straightforward. Before you buy a mover it is crucial to choose the mover that is suitable for your caravan and there are several factors to consider. Firstly, manoeuvring a twin axle caravan is never as easy as manoeuvring a single axle caravan. This is primarily due to the fact that a twin axle caravan's four wheels make it difficult to turn. This means that a mover designed for single axle caravans should not be fitted to a twin axle caravan – this will limit manoeuvrability to forwards and backwards only.
Choosing the right mover
Most twin axle caravans have a normal chassis height of about 18cm. However, there is some variability in chassis heights and some caravans can have a chassis height of only 12cm. New caravans may have a Vario Chassis which means we need to use additional plates to fit a mover.
A 2WD mover can be fitted behind or in front of the caravan wheels. A 4WD is always fitted with motors behind and in front of the wheels. Ideally, the place where the mover is fitted must be free of metal reinforcement plates or other objects such as a lower entrance step, for example, found on Fendt and Tabbert caravans, and so on. Please check that you don't have any plates like this:
Of course the removal of any such plates is not recommended or permitted. Instead the mover is lowered if there is no plate-free space available. Truma movers have to be lowered by 3 or 6 cm. For the Reich fully automatic movers it is possible to lower the mover in steps of 1 cm and it is even possible to lower the top of the mover by 5 cm with the loss of only 1cm more of ground clearance.
