Dethleffs trailers up to 3.5 t – class O2: touring caravans from the pioneer of German caravanning in Isny im Allgäu in the trailer register, type codes such as 540 TK and 500 UL, weights from 290 to 2,295 kg
Dethleffs of Isny im Allgäu is one of the oldest German caravan makers and built one of the first German touring caravans back in 1931. The brand is now part of the Erwin Hymer Group and, through it, the French Trigano group. The O2 vehicle class covers trailers with a gross weight of 0.75 to 3.5 tonnes for registration purposes – this includes every touring caravan towed behind a car. Dethleffs type names usually combine a number for the body size with a letter code for the floor plan, such as 500 UL, 540 TK or 560 SK; no consistent system across all model years can be read from the register alone.

The register lists 526 versions with unladen weights from 290 to 2,295 kg and gross weights from 800 to 2,800 kg. Lengths are recorded for 177 models and range from 5,130 to 9,800 mm, widths from 1,920 to 2,550 mm.
Alongside Hobby, Tabbert and Knaus, Dethleffs is one of the highest-volume touring caravan brands in the German-speaking market, and its range covers everything from light compact caravans to large family models with bunk beds.
When buying used, check for signs of damp on the floor, walls and roof lights, the condition of window seals, the gas system including regulator and inspection sticker, the overrun brake mechanism and handbrake, and tyre age, which in caravans is often older than the mileage would suggest. Axle, dampers and jockey wheel belong on the checklist too, along with the drawbar for corrosion.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
