Hello, we have a 2008 Gearbox 395FSA3GG, while looking for things to fix (an annual event) I noticed it appears the passenger side wall seems to be flexing, the framework not the fibreglass. Has anyone seen an issue like this? If so any ideas on repairs? I have zero faith in "RV Techs" in Canada, never met one yet that has actually been able to solve oddball issues.
