Just thought I'd show my XLR after I installed the Bolt It On rack in the camper.
1) I really like the rack and adjustability it brings with offsetting the bikes, etc.
2) I really dislike how Forest River put the black water right underneath so that I couldn't mount the rack even further forward
3) I mounted it by drilling through the holes with a washer to underneath with some threaded rod so that I could remove when using the bed.
4) This fits my 2003 KTM 525 MXC with about a 1-2 inches to spare.
