Never sugested caravan with floor lower than wheel centre Lutz.
Your statement that triple axles on semi trailers are provided for one reason only, that being "keeping the axle load within legal limits" is total (well. Begins with B and ends in ck's)
Use of triple axles and multiwheel semi style trailers with no cross axle has nothing to do with weight issues or road weight law in many cases.
They provide a firmer base with less flexing and do away with the common place heavy chassis rails that reduce carrying volume.
They also provide the firmer chassis needed for elevating double skinned trailers that become double decker 7 metre high units when parked and run on European roads at far under the maximum weight limits.
The super structure of the bodies are lighter and thinner as they ride on a more stable platform that flex's less and suit numerous applications. 13 Metre articulated trailers are not all used to max weight carriers, just like caravans are not designed as heavy weight carriers.
There is no reason why with modern materials and build processes similar results can't be acheived with a caravan and at reasonable costs. And after all we've had caravans on twin axles that are not as heavy as you make out Lutz and even with high mileage we've not experienced the problems single axles of the same brand and period have experienced.
Plus if they can "glue" together a 13+ mtre long semi style trailer and chassis with no cross axle, sorting a more modern caravan build process should be quite easy and better than anything we have now.
