I had a Thule Cargopro 2 quad ATV trailer. It was really nice and convenient with folding sides that doubled as ramps. Loading and unloading was very easy but with my 2 up quads it was tight width wise. I ended up buying a 101"x12' snowmobile trailer. I got mine for around $1000 used with a banged up aluminum shell. I took the shell off and put eyebolts every couple feet for tie off points. It has a tilt bed so I can load 2 sleds (don't have yet) or 2 quads by riding them up until the trailer comes down on the tongue. If I park our 2 quads all the way to the front, I can also fit a buddy's quad on sideways on the back 4 feet of the trailer. I bought a good set of aluminum ramps for sideloading. Not as easy as the 2 quad trailer but much more room and no gouged plastic.
