The brand I was considering is http://www.mototote.com/ which is rated to
500#. Any way I slice this I see putting 425# + hanging off of one end of
the van or another. I will probably trailer the bike rather than abuse a van
that has been very good to me. My ultimate goal was to be able to camp and
then take the Enfield out for a scoot around the Texas hill country without
having a trailer to contend with.
