Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Mounting bolts from frame to Rv front sidewall are in 3/8” lag bolt mounted in pine wood (all are striped, won’t tighten). This allows the complete front Rv wall to move allowing further frame issues. Holes in frame rail are 1/2” , grand design installed smaller lag bolts 3/8” this has caused the bolts to eventually fail. This is happening on approximately 30% or more of Grand Design RVs. The factory needs to provide a recall on this problem.”
