Hello. I have a 2011 Patriot and I'd like to know if anyone has any experience with bike racks that can mount on the back of a Patriot and what are the advantages/disadvantages to different models. Ideally, I'd like it to hold up to 4 mountain bikes, but if not, at least 2. I'm sure this has been discussed a million times and I'm sure I could easily look it up, but I'm a bit pressed for time and I would like to know personal choices some of you might have. Thanks a lot.
