Gas or DP

We purchased our DP ten years ago, when it was new. In the past ten years, we've made numerous mods and have had some repairs. We go to RV shows every couple of years to checkout the new coaches. Just as ten years ago, we could afford a new unit, but at just ten years old, our coach is reliable, comfortable and known. No reason to look at replacing just because it's ten years old. Not sure if this answers your question or not, but I certainly wouldn't dismiss a DP I liked because it was ten years old.
