Has anyone used the Menabo Boa on the spare wheel of a Prado (2002)? I've just got my Felt Edict 3 so can't hang the carbon puppy off my old rack - but don't want the hassle of tow-bar mounts that block the back door (even when tilted!). Seems the wheel mount is the way to go so just want to be sure it'll fit before spending the dosh! ta in advance
