trailer sway mitigation TSM

Nelson customized a number of his trailers over the years for extreme towability. The best by far was an LS4 aluminum clamshell trailer that had been turned around so the glider loaded and unloaded over the tongue. Moving the heavier parts of the glider to the back allowed placing the axle further aft while maintaining a reasonable tongue load. Nelson delighted in towing it with his wife’s Datsun F10. The poor little F10 was quite stable, but excess speed was never a problem. I towed it myself with a number of smaller vehicles and the trailer was essentially unnoticeable except when accelerating or slowing down.

This is an option for many of our trailers, but the market reality is we’re willing to sacrifice stability for the convenience of not assembling over the tongue.

Moving the axle further aft means you sacrifice the trailer's maneuverability at narrow street corners - you will drag it over curbs and sidewalks, possibly hitting lamp posts. I think the axle position is part of the compromise that professional trailer manufacturers like Spindelberger take into account.
