Looking for recommendations on a two bike rack

In my experience, a front hitch keeps the bike out of the way for the most part. I find a rear hitch to get as dirty or dirtier from the dirt/dust. I live on a gravel road, the back of our cars is alway noticeably more dirty than the front.

As far as hitch goes, I have a Capstone. You will have to add a front hitch to carry on the front. New brands are coming out all of the time. I would get something that has hoops big enough for a fat tire bike in case you go that way in the future.
