Towing ability is way more about weight and very little about TT length if properly setup.
Have to disagree here! While weight certainly plays a huge role the length is very important as well. Wind effects on the side cross section can be serious, especially on a TT vs 5'er. Longer the trailer, worse effects with all else being equal.
One thing I've noticed is that towing MPG changes very little with the weight of the trailer. Frontal area of the trailer and overall drag play a much larger role. Going from a 5,000lb TT to a 9,000lb 5'er resulted in MPG going slighty up, not down as expected.
