I have had three enclosed and a open trailer over the years. Currently have a Pace Legacy Gold, 6 X 12 single axle with brakes, fully finished interior, seamless horizontal exterior walls and brakes. I pull with a SUV and have for the last few years. My current Denali is taller than the trailer so I bought a flat front as drag is not a problem. V-nose is a good idea if you pull with open pick-up or car, will definitely cut down on drag, but not much help on a Full size SUV and will not work with a motorhome (go thru a deep dip and frt of v will run into the back of the coach). Main thing to buy in my opinion is the low-hauler style. Loading, even if you are tall, is not a problem, you load and tie down the bike which takes a couple minutes then you drag a tall trailer, Vee or Flat, thru the wind? Why? Not like you are using the trailer on a daily basis, just to get there, unload, ride then reload and go home, unload and then it sits for awhile. I prefer single axle for one bike due to ease of moving around at home a single axle provides and brakes are cheap on a new trailer and do help stop. You need at least a 7 wide for two bikes, I bought a 6 this time on purpose, I got tired of dragging buddies bikes with the added weight, more expensive, tandem axle with increased drag wider trailer so they could sometimes say thanks. My single axle 6 wide is lighter, pulls like nothing is back there and only cuts mileage by a couple mpg. Much better than my last tandem 7'. BUT the main thing that makes trailer towing more enjoyable is HORSEPOWER in the tow truck. MORE is always better. Had a 6.0 Escalade and now a 6.2 Denali. Totally effortless for either one, althought the 403 HP Denali is even better than the Cad's 345HP by a sizeable margin. I have made the tow to Sturgis, 2100 miles, just set the cruise and go, have a buddy with a Trailblazer with the 4.2 6 cyl and he is tired at night from just trying to keep up, loses speed up hills, he says leg gets tired from mashing the gas. Not fun to me.
