Haulmark Edge low profile. Mine is 7 X 12 tandem axle and will haul two big bikes easily. We tow to Daytona in the late winter and it pulls great behind my F-150. I also use it for racing and camping and it looks like new after several years of use.

 

towing a 5x10 singel axle v-nose with a v-8 F-150 i went from about 18mpg to about 13mpg

 

Wow... lots of great info here guys... thank you. Please keep it coming.

Sounds like pulling an enclosed trailer of any kind makes for a big drop in mileage... and I'm guessing that going from a 5' tall to a 6' tall v-nose to flat nose may not affect mileage quite as much as going from no trailer to trailer? Being 6' tall, I'd kind of appreciate the 6' version making it possible to almost stand up in there. The ability to occasionally sleep in the trailer along with the bike is also something I think I'd like... so that means probably a 6x12 tandem at a minimum?
