Wouldn't it be important that the axles are parallel to each other? Otherwise they would be trying to turn constantly, causing tire scuffing. A single
axle would just 'dog track' if the
axle is not perpendicular to the centerline of the trailer.
With dual axles, because the pivot point is between the two inside tires, turning too tight, backing or forward could, as I understand it, cause the inside tires to pop off their rims - one tire is sliding in toward the trailer and the other is sliding out away from the trailer, whereas in a single
axle, the pivot point is centered under the inside tire.
Also, driving out of driveways with hard crowns throws all the
weight onto one or the other axle.
As far as backing, I had a boat trailer that had a long wheelbase and it was easy to back. Homelet is short and turns when backing much more abruptly. However, it just takes less turning of the steering wheel to get movement from the trailer. It can jackknife quicker, but that is a function of the distance from the axle to the hitch, IMHO.
As far as towing stability, Homelet tracks behind our TV like it was on rails. I have had NO issues vis a vis stability or wind affecting the tow.
