You can design a single axle trailer that has low tongue weight, but when you get below a certain threshold (most say 10% of overall trailer weight), the tail will begin to wag. The tail wags because the balance point is too close to the front ! Measure the loaded deck only no tongue and the axle should be no less than 60% forward and 40% rear. The tongue should be lengthened to give you 15% to 20% of the unit weight at the ball cup. (Time to drag out the bathroom scales). Most manufactures skimp on tongue length for one good reason that extra 18" to 2 feet costs more and may require slightly heavier wall material.
I don't think dual axle is going to resolve the issue for you.[/quote]I currently have 7 trailers 5 are single and 2 larger are dual axle. I have always been fascinated with finding a very tiny dual axle frame for a teardrop.
When towing a dual the second set of tires serve to snub the sway as the trailer would have to slide one set or the other. ( Watch one make a tight turn to better understand)
A blow out goes from a potential wreck to a simple headache. In fact in an emergency you can tow on 3 good tires. A very short hop just proceed on the flat and for a longer emergency run simply remove the tire and rim and go looking for a tire repair service. With the duals you sort of step over the bumps and pot holes verses hopping over and falling in them. This limits the shock and jerking often associated with towing.
Many dual axle trailers, when uncoupled, will support themselves as the tongue may remain in the air making lifting the tongue much lighter and making hook up easier.
Yes Virginia I would have a mini dual teardrop if I could just trip over the right frame.
