Fitting a mover under a double axle caravan is a nice challenge with most caravans, but with a considerable number of caravans, fitting the mover is very specialized work. Not every mover can be mounted just like that. This is because there are many limitations in what fits physically. Not all manufacturers offer a wide range of mounting and clamping plates. Not every mover can be mounted optimally. To date, we have been able to mount a mover under each double-axle caravan. A double-axle caravan never grades as nicely as a single-axle caravan. This makes sense, since with four tires it is simply less convenient to make a turn. You may not mount a single-axle mover under a double-axle caravan based on the admission, it is not suitable for this.
There are two types of double-axle movers, a variant with two engines (2WD) and a variant with four engines (4WD). In our opinion, a 2WD is a very good solution for caravans with a weight of 2200 kg.
A 2WD has less power than a 4WD. With a 2WD, making a 90 degree turn takes longer. With the Truma XT2 you have to count on 2 minutes and with a Reich mover more than double. With a 2WD two wheels are driven. So there is a risk that the driven tire does not make good contact with the ground, with a 4WD all tires are driven. A 2WD mover from Reich or Truma weighs around 34 kg. We recommend our set 2 for the 2WD models.
A 4WD has 2 engines more and therefore weighs double. A larger battery is also often needed with a 4WD. The total weight increases by more than 40 kg. A 4WD is characterized by a finer steering, making a turn is more comfortable. With the 4WDs you can often make a turn even faster by pushing the buttons crosswise. With a 4WD we recommend our battery sets with the Optima 75Ah battery, that is set 3 or set 4.

Height of the chassis
The chassis height of a double-axle caravan is usually 18 CM, but there are also many caravans with a height of less than 16 CM and there are many caravans with an even lower chassis. We often prefer to mount a mover that does not require lowering plates, but this is not always possible. Checking the chassis
The 2WD movers can be mounted both in front and behind the tires. A 4WD mover is mounted both in front and behind the tires. This space must therefore be free of restrictions. The image below shows a common reinforcement plate for the wheels:
This is usually both in front of and behind the wheels. The removal of these plates is not allowed, but there is a possibility to replace it with other holders. Ground clearance
Ground clearance is always an important point. After mounting the caravan mover, there must be at least 11 CM ground clearance. We advise you to find a solution where you have a minimum clearance of 14 cm after installation.
