Welcome to the forum, Marlene. I think you'd enjoy a class B van since you already know you enjoy RVing. Bs are great for one or two people, and we often meet solo women travelers in B vans.
Coach House has a good reputation for quality. Without a lot of mechanical savvy, I'd hesitate to buy a 17 year old RV, though. Rather than put $18.5 thousand into an older van plus updates to various systems, I might be inclined to look at something new and under warranty like a Travato.
You already know that no RV is trouble free. But a newer one might give you a little more peace of mind if you plan to eventually hit the highway for long trips.
