In April of 2007 we purchased a 2000 Keystone Springdale 26TBL from Bourbon RV in MO. We were aware that previously the trailer had leaked in the front but all all areas(including the roof) had been re-sealed and until March of 2008 we did not have any leaking issues. In the front(bed area) where there is a bend in the wall the partical board is wet and the wallpaper of course if peeling off. I thought if it was leaking from the roof or side seams the storage area above would be affected. The entire storage area is completely dry including the side seam areas. We have re-sealed every exterior seam we can find. The trailer is parked at our farm and we are no where near any dealer - My husband is very handy but we don't know what else to do. Any suggests on where this leak might be orginating from or what products we are use. HELP IN WET MISSOURI!!
