I've towed motorcycle trailers {3 different styles} for the last 7 years. Our current {and favorite} is a 6 X 10' - 8' tall cargo trailer. Here is a shot on the new I-11 near Hoover Dam taken on our return trip from Yellowstone and Grand Teton National Parks:
On this trip I was hauling my Indian Springfield field motorcycle. I have since traded it in for a Can Am Spyder and when we don't bring the Spyder our little Polaris Rzr SXS also fits nicely. The best thing about having the cargo trailer is that for all intents and purposes it is a private garage that follows our Cass C like a faithful puppy {it also tows just fine behind our Honda Ridgeline}. Our toys stay out of the weather and the prying eyes of the bad guys.
In addition to all of the use it gets when we are on the road it has served us well hauling landscaping materials {gravel, rock, lumber, tree trimmings etc.} and when we moved last year I made 8 round trips emptying one house and refilling the new one.
I can easily move it around with the Rzr and just completed a new pad to park it on:
It also makes for a fine quasi permanent garage {for the Rzr or the Spyder} right there alongside the driveway. Here is a shot with the Spyder loaded and as you can see there is still lots storage available:
