European trailers are designed to be low profile, very light through expensive materials, and very narrow, even if they do have midsize lengths. They look luxury but usually don't have a combination of 1 RV queen bed, full size dinette, a RV sofa, and a full bathroom, or additional bunks for families. Speed limits are also lower allowing cars to pull more stable with those lower speeds. They are also balanced for light tongue weights which isn't always best for the floorplan. Their couplers usually have built in friction pads that aid in sway control due to their lighter tongue weights. Their lower speed limits also aid in sway control.
After looking at many, I don't like that most don't have a full size dinette, separate sofa and most importantly, a BATHROOM. I really don't like how expensive they are. They price many people into tents or Pop Ups. I do like that they're very luxury though, but the lack of functionality makes them something I wouldn't bother with. I would rather have a pop up with more beds, sitting areas, and a bathroom.
