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.
I think a TT will be over 65% load most of the time. CCC is typically less than a third of max. At least it is on the 20' ones.
It fully depends on the trailer. Some trailers have more axle than GVWR and some trailers use TW to meet GVWR. It's impossible to put a blanket rule on it... just like someone tried earlier to state most trailers under 23' are single axle which is not true.
My trailer is larger, but at GVWR counting a 15% TW the axles would only be right at 65%. That means I would have to be at GVWR all the time to get the ride benefits out of a torsion axle. (I am always well above GVWR for the trailer so may actually benefit, but the average user would not).
TT's will be higher loaded most of the time, but not always. Just something to think about when looking at axle design.
