I'm so sorry for the loss of your wife, nothing anyone ever says can take away the pain. Know you will be together again some day at that big campground in the sky.
I lost both my parents within the past year. In the end I cared for them both. Growing up we always had some sort of trailer, my fondest memories were camping. When they passed I wanted to do something meaningful with the bit of money I was left- I bought my tt. It seemed a worthy tribute of their memory and the time we spent- together as a family, how it should be. I could have done something different or perhaps wiser with the money but there is no price for time together, something I want my kids to understand. Your story is bittersweet, know your wife is waiting for you and the great times you made together were the best years of her life. So happy you made the decision to do that sooner than later.
Hugs and prayers to you!
