Northern Lite 10-2 Bulge/Buckling Repair Advice

I respectfully do not understand what fixing a "crushing" basement has to do with this post. I am looking for advice from someone who has actual experience repairing a bulge where the cab over meets the main body of the camper. I am not fishing for social interaction, just first hand knowledge from someone who has actually had this particular issue. If you want to talk about a basement perhaps you could start a separate post.
thanks
