The sxs is too long, but a bike or the right quad should fit. I went with this size to keep my total weight down and keep it a tandem axle. A lot I've seen go 36' (I'm 30') and triaxle. I'm happy with the length I went with so far. It is an enclosed trailer, loading it isn't an issue. Where the Jeep sits, the weight is perfect, I can easily forget the trailer is back their until I go up a hill then the 12K lbs kicks in. Being a gooseneck, weigh distribution is very forgiving too.
