one axle vs. two axles on short TT (20')
I was wondering what the pros/cons were of one axle vs. two axles on a short/lite TT. I'm talking about something less than 22' and 3500 LB dry. I guess I should also ask about wheel size too.

The other potential issue with torsion axles is they require weigh to work. A torsion axle that is loaded lightly has very little give and rides much worse.
When shopping cargo trailers for my dad last summer we where talking with the trailer manufacturer and they only reccommended torsion axles if the trailer was going to be loaded at least 65% of the GAWR most the time, otherwise the leafs where a better option.
You are correct. The rubber torsion axles start riding real nice when you get over 60% of the rated weight on them. That is also a factor with leaf springs on a single axle. It is the equalizer on a tandem axle, leaf spring setup that keeps that rough ride from occuring when the trailer is real light.
I forgot to mention another positive attribute for rubber torsion axles is that they are "independant". Dexter used to make some leaf spring axles that were split in the middle with a pivot point so that the trailer would have leaf springs, with an equalizer that are also independant. Those trailers handled and performed very well.
