Car transporters are for transporting cars.
These can be very different vehicles, from small to large, from camper to racing car.
Depending on the type of vehicle that has to drive on the trailer, the approach angle is important, the strength of the trailer in relation to the weight that is driving on it, but also where the weight is on the trailer.
We usually build a trailer that can hold 2 vehicles or, for example, one large camper.
Occasionally we build a trailer that can hold 3 vehicles, but given the weight, these are usually smaller and lighter vehicles.
Nowadays, cars are often larger and heavier than before. The weight of a car is usually also heavier if they are electric due to the battery.
The trick is how a car transporter can be built light, but still strong enough for use. That is why we are increasingly building aluminum trailers.
