We have just started our coleman Newport '85 restore. We are starting with roof repairs but are attempting to do them all with the top still attached to the trailer since we don't have the space to take it off and do the repair. Here is our blog to show our progress so far: http://campingchessells.blogspot.ca/ Any tips are appreciated. We are planning to replace the entire interior roof, seal the outside edging then paint the entire roof with some sort of rubberized paint to seal any small holes. Then decor (cupboards, table, new mattresses, etc).
