First, is the roof one piece, or sectioned and seamed? I have heard both good and bad about the roofs, but some high-end trailers are using them I also hear.
Some of the 'old widow ladies' can be good businesswomen--let your conscience be your guide. I would consider it a pure business deal, if your own mind will let you look at it that way. I have been involved in 2 deals with widows and both were relieved to be rid of the trailer and the memories--and I did what was 'fair' for me without putting lowball pressure on them.
