Then I would consider welding it. You can't just reposition it, as the location is a critical measurement for proper operation. You also do not want to through-bolt it as drilling completely through the frame would likely weaken it. I read a post a while back by a guy tha did that and Lippert voided his warranty.

Another possibility is to go through the bottom of the frame with a hole saw that would allow you to get in with a nut and wrench and then have a plate welded on the bottom to cover the hole and reinforce the frame where you cut it. I think that would fix the problem without compromising the integrity of the frame.
