i'm in the trailer buying boat right now and like the original poster I haul three mowers. I haul a Ferris IS2000z, Toro 52" Grandstand and Toro 40" walk behind. Right now on my 16' trailer i have to pull the Z on first, then put the Grandstand tight up to that with the front wheels staggered between the back wheels of the Z then i have to put the walk behind on sideways on the back.
my plan is to move up to an 18'. I'm tossed up between two trailers, one is a demo and one id order in new...the place that has the demo would take my dump trailer in on an even trade, where the new one the company would only give me about 2600 towards a new trailer. Weighing towards the even swap
