As Dave said, most of the mini ball mounts end up under the LP tank bracket. It is OK as long as you have the clearance.
This is on the side of a Keystone Cougar TT
This pic is from the side of a 2004 T-2499 from one of our forum members campers. This A frame rail is 5" tall channel iron.
Your 2005 T-2499 most likely has a 4" tall channel iron A frame. That should still work OK. There are many of the smaller campers with these friction bars on them on 4" tall A frames.
Hope this helps
