Four Huffy bicycles probably weigh as much as the VX ........

Seriously, the Mototote carrier looks neat - but I don't think I would use one - not on a VX or any other vehicle. The carrier does have it's merits - and eliminates a few of the hassles that are associated with a trailer, but ......

I'm also surprised the Navigator had a 500 lb tongue weight (max). Whoa ! The hitch must attach to the frame in about twelve locations !

I would purchase a trailer - or have one made.

I have an aluminum (custom built) bike trailer that I use to haul motorcyles and (occasionally) bicycles. I also have a snowmobile trailer. I plan to pull both with the VX.
