Rainy... I've read your original post in this thread a number of times, along with the responses thus far (good points all), and after 2 years of considering this it may be fair to say that you have enough information to make your move.
https://rv.org/ is a website you may have seen, and could be helpful in your quest. Many times folks learn with their first RV and may actually have two, three, or four before they have their keeper, or at least one that checks the most boxes for them, and at that particular time in their life. I encourage you to move ahead with this. You've thought about it, researched it, analyzed it, and have narrowed your choice to what you have mentioned. Be honest with yourself and your plans, know the rigs capacities, simplify your wardrobe and your life, and by all means Run Rainy Run.
I just found this website and I think it's wonderful. My husband just turned 66 yesterday and with the downsizing of his company and the reduction in hours and pay, we have decided to start our new journey sometime this year. My parents sold everything they had and lived in an RV for 9 years. They had all different kinds so I'm kind of familiar with which is which. We've been speaking to a lot of our friends about this and they have been very helpful, but this has added to that information. We're planning on staying in one place a few months at a time possibly working in the campground and getting free rent. My kids will be back in the states in April so a lot of my stuff will be given to them. We plan on selling or giving away everything. That's the hard part. We are very excited but very nervous at the same time. Looking forward to seeing all the posts and maybe getting some help from everybody out there. I'm going to show this site to my husband; I think he'll like it.
