We tow a 2005 MCS four down using a Blue Ox set up. Campingworld/Crystal Valley RV installed the mount. It looks pretty neat. I do have pictures if you'd like to see them. I have added an auxiliary brake yet. Still looking at several that look like they'd work. We don't have a lot of miles towing it but have had no problem with the Blue Ox.
