My "requirements" have changed what with my family getting older, my retirement from the local BSA Troop's geezer patrol, and my bride decided she doesn't want to camp anymore

I've got a lot to think about!
Has anyone else here been there---done that and have any tips?
Back to camping gear:
My tents, both back packing and car camping, have had it.
The cook set is over the top---not sure what needs to go---i could probably feed platoon with what I've got, I need to donate some of it to the Scouts.
Rain gear also needs replacing.
My back packs are old but still have a lot of miles left in 'em (fortunately my son returned my Kelty Redwing in good condition after he replaced it with an Osprey. My ultra-light Mountain Smith(? that label came off) Ghost is still in excellent shape.
The Coleman car camping stuff is bullet proof but the backpacking stove is useless for anything but boiling water. I'd sure like to find something better.
What about you? Have you done an off season camping gear check, or plan to?
