We took the plunge and purchased the Class A, 1984 Holiday Rambler for $2,700. The seller's husband took ill 2 years ago. They can no longer travel due to his health conditions. We're wanting to give it the TLC it deserves and would like to start with the roof. Afterall, if that leaks it could ruin the entire MH. Does anyone have suggestions/opinions about sealing a MH roof? Thanks in advance!
