I think for the Price some bespoke Trailer are offered you can buy something like this: Anssems Autotransportanhänger AMT 2000.400x188 Eco (weight 365kg without ramps, with dual axle, brake etc.)
When completet for a threewheeler it still would be usable with a 4wheeler.
You have to add a middle ramp etc., Problem is maybe the ground clearance!
