I have a 7x14 enclosed that I primarily use for dirt bikes and quads. I occasionally put two sleds in it. One cat sled with 38" ski stance and one ski-doo with 36" ski stance will both drive in side by side, but is tight with the skis overlapping in the middle. If I load one forward and one back there's plenty of space around them for gear, access through the front walk-in door is better, and I can leave a heater mounted to the wall. Only thing I would change is having a v-nose on it. Mine is a flat-front cargo trailer.
