At a width of 2,550 mm, the vehicle matches the road measure common in Europe. An unladen weight of 3,800 kg leaves a payload of only 100 kg: practically the entire permitted weight is already taken up by the fitted-out travel trailer itself, leaving little room for luggage, water and equipment.
Category O3 trailers run with air brakes or a correspondingly designed hydraulic brake system, not the simple overrun brakes of light travel trailers. Towing requires, depending on the combination's gross weight, driving licence category BE or C1E, which is worth checking before buying a US vehicle of this weight class for use in Europe.
Buying a travel trailer used, moisture comes first: water ingress at windows, roof hatches and the front hitch panel often only shows up as a soft floor or a musty smell long after the damage occurred. The gas system, axle bearings and tyre age need checking just as much, since travel trailers often cover few kilometres but spend many years standing outdoors. With a payload of only 100 kg, any equipment added after manufacture is also worth weighing, since it eats directly into the small margin left for luggage and water.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.

- 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.
