To add my own two cents...
I know a lot of old timers get annoyed when a topic comes up for the upteenth time but unless the posting is egregiously duplicitive (similar topic on the front page as an example), I think it is healthy to have the same discussions come up repeatedly over the years. New people, new technology, new ideas means new ways to solve old problems. In many ways, forums like this are like the old campfires of old where traditions and tribal knowledge were passed on from one generation to another. Every day around the campfire there are new people joining while others are leaving, it is just the way life works.
Speaking of life, I would also venture to guess that as long as this forum has been around, many of the original posters have likely moved on to later stages of life or are now wandering the highways in the sky. As much as we enjoy the freedom a truck camper brings to us, the reality is that the nature of the platform is such that it can be difficult for people with health conditions. Lots of steps, high beds, limited space and other limitations are not always conducive to old bones and hence why so many people move on to trailers later in life.
