2 pl enclosed aluminum Triton, real similar to Rotax Kid's trailer, except it is very light, I think 1200lbs dry. 3500# torsion axle. 1 person can turn it around on pavement loaded with sleds. It's the "bonded" skin, which looks good, but in 100deg summer heat, the glue softens and drips on my sleds, in a couple spots).
I've held off insulating and sheeting the inside to keep teh weight down, but that would cure the "drips".
I've put a fair amount of miles on it with no trouble. Just being enclosed, it heats up easily with a propane heater if I need to work on the sleds out in the field. (-20F on the Mesa last year and I was inside working in my shirt sleeves.)
It'll fit 2 - 162's and a Sno coach easily. Might get 3 shorter track sleds in it very carefully.
I like this model because it's light, tows easy, can unhook it and turn it around by hand in a tight turnaround or if the snow's too deep in the lot or road.
