Deb,
It's sad for her to not have it anymore but she can't help but feel the right people got her 5th wheel so it has to cheer her up some. Might be nice to give her a call sometime after you get back from your Florida trip and relate some of the fun you and enjoyment had and how you appreciate the excellent care she gave the 5th wheel while she had it and that you will keep it good as new. It would even cheer her up more and make her feel even more strongly that her happy days with the 5th wheel are living on with you and Ed.
We've nearly always purchased all of our RV new or ordered them but one in particular was purchased from a local widow we knew who's husband got lung cancer and lingered for 3 years before dying. They only got to use the new RV most of one season and there it sat, their basically new RV with a cover on it. Finally she needed the money bad and we knew it and we gave her exactly what she wanted for it, no haggling at all as we knew how bad she needed to sell it. She had tears in her eyes and it really touched us deeply. Money is so far from everything! We kept it for 7 years and sold it to a friend who still has it and loves it.
Her son, who we saw and talked to in Meijers, told us how much she appreciated knowing we were very happy with her & her late husband's RV and that his Mom mentioned that she'd sure like see it again sometime. It was in the summer, So we drove it over to her home the next day, which is only about 8 miles away, and let her check it inside and out for close to 3 hours and asking us questions about where all we'd gone with it. She smiled from ear to ear constantly and thanked us profusely over and over. Seeing her so happy made us both very happy also and still does.
