That is a sweet set up 10petenat - and definitely better than mounting the bike rack at the rear of the van where the bumper supports are only rated to 30kg (Jayco manufacturing rep infoms me).
I have a 16.49.1 and I did this mod: bracket to move gas bottles closer to van, and support bracket made to mount the 4-bike rack holder as close to the van body as possible. This keeps the bikes away from interference with the towing car in tight turns. The first bike sits just off the gass bottles.
I still have to take all the bikes off remove the rack to get the beds out.
I have looked at other mods on this forum and others and IMHO this is far simpler and safer! (howver i would say that wouldn't i!)



So have a look and let me know if you have any questions.
