Marmota - the trailer in the link I sent isn't mine. It's an old post. I included it purely for illustrative purposes to show the e-tracks. Personally, I'd never chose a single axle.
I know. I saw the post was from someone else and old. It says it has electric brakes so it's better than it looks. And they mention at the bottom about the tongue weight matter. I was just trying to give useful advices.

My main problem was the size. Impossible to even think about a huge spaceship as AlexKnoll's! Holly cow what a yacht!

Remember that in Europe our cars are so much smaller.... and consequently, our parking places, the width of the lanes in the motorways, etc. I can't imagine arriving to a toll’s paying barrier and try to fit in the lane such large monster without scratching both sides!
