I do not agree with those that say that if you worry about making the right decision, to not do it. I think worrying about whether it is a good decision and doing a lot of research is a good thing. I worry more about those that do not worry about the things they do not know.
It is hard to make a recommendation because I do not know your financial situation. In our case, we were very nervous about purchasing a diesel pusher. It is a big decision. We purchased ours 3-1/2 years ago and we would not change the decision. We love traveling in the coach and we have gone many places we would not have gone without it. We have had health issues last year which reminded us that we do not know how long we have and we need to do what we love while we can. Living in the coach is so very comfortable. We love being totally self contained and my DH loves being able to use the bathroom as I drive. We feel that we only live once and the coach has enriched our lives.
