Really feel for you as we're older and looked forward to traveling and not working full time in our retirement years. Not happening as we'd hoped but adjustments made and we're getting to go some. We also spent a bundle on our 2004 Chevy 3500 Duramax but with now 180,000 mikes on it no earth shattering out life altering trouble. Just tires, six when we wear out a set. The biggest expenses were all after warranty but addressed by independent mechanics who did work for half or less than estimate from dealer. Injectors,a given repair over time and not unexpected, some front end work and other expected wear and tear stuff. And now with ten years in service as a brick mason's work truck its finally hauling the truck camper it was designed for. Oh, it still is the Work truck between trips, and we are thankful every day it continues to function as needed. Don't know how long it will last or what our available financial options will be when it dies, and at some point it will, but we'll deal with that when it happens one way or another. Try not to let the uncertainty or what ifs get you down and take the joy in what you both seem to really enjoy doing. Sounds a little like it's kind of a personal issue with going forward. This is coming from the DW of a DH who is older and gets tired and discouraged more easily with indecision taking over for previous certainty. I think with many of us as we age being closer to our end brings many more and different,difficult, questions and issues to deal with than younger folks haven't faced yet. We all have to deal the best we can OURSELVES and not let others well intentioned advice have undue influence on our own circumstances, unless of course they are willing to foot the bill for fixes. Hoping for the best for you and yours and a more positive future.
