Sorry for the slow reply. It is a Stromberg Carlson Bike Bunk and we purchased it from eTrailers.com

It is very easy to install. Very sturdy. This is actually just a RECEIVER that will then hold the bike rack that you already have. It will hold other things too although we just use it for the bikes. We already had a nice 2 bike rack that fit into a 2" receiver... so it slips into the Bike Bunk. Hope this helps. It gets a lot of attention from other RV people where ever we go.

also have a fun finder 189 fbr (2010) and have been looking for a bike rack. Do you mind sharing what kind you have in the 6/20/18 pictures you recently posted? How sturdy is it and does it impact how the trailer tows? Thanks
