Single axle vs tandum

Although they're also designed differently otherwise, single axle is the norm in European trailers in this size range. In my opinion a properly balanced single would be preferable to a double if only for the fact of their being easier on tires. Scrubbing, for example, is a phenomenon limited to multi-axle setups.

Some folks think that doubles somehow serve for a sort of "redundancy safeguard"- mistakenly, in my opinion, since a double only divides the load and can't itself take up where the other leaves off in the event of a flat or some other catastrophe.
