Bought subject trailer last October. Just discovered water leak. Not sure where it is coming from. Water stains on mattress and wooden frame underneath as well as mold starting to form. Additionally, puddle of water found in forward storage compartment. Under belly may be holding some water and sagging slightly. At this point, I honestly do not know the extent of damage, only time will tell. Will Grand Design stand tall for this? Repairs? Not sure about that. I think it should be replaced. Thoughts and opinions appreciated.
