Well I just watched my truck drive off into the sunset with some stranger behind the wheel. Other than the HPFP issue that was a darn good truck- I put 110k miles on her and not one of them was easy!...
I think some people are just more sentimental than others. I have owned many trucks, cars, motorcycles, snowmobiles, only 4 RVs, but never minded seeing any of them go. It was always done with the old, on with the new.
When I think back, some of my new ones, would be collectors hot items now. However, even if they would be fun to have stored away now, it makes no sense to me, if you really don't use or need them.
