A few thoughts ...
Many folks here would agree that they wish they had started sooner. We moved up to a Class A from a popup trailer maybe 10-15 years ago. It was a 28 foot 1999 Coachmen Mirada, no slides, a basic entry level coach. As I recall it had about 30,000 miles and we paid around 29K (best I can remember), daughter has it now. We used it on weekends and longer trips ... several weeks out after we retired. Used it to go to grandkids sports events. Nice place to hang out when they have a game in the morning and another several hours later.
While wife was still working as an RN at 2 different facilities she mistakenly scheduled a swing shift at one, and day shift 8 hours later at the other. Got permission to park at 2nd facility, picked her up about midnight, drove to 2nd. She went to bed on the way (a few miles). Got up next morning, showered, had breakfast and went to work at 7am, much more rested than if she had gone home between shifts.
Me ... I went home for a cup of coffee and a nap! ;D
Point being there are lots of ways you can use the RV even between trips if you like. And it's nice to just get away for a couple of days at a local nearby campground ... no lawn to mow ... can't paint the house. And really great when on a trip ... clothes, food, bed ... everything you need just feet away.
Floor plan is very important. When we looking for the coach we have now, I learned to send wife in first ... wait about 30 seconds, because that was about all it took if she didn't like it. If she wasn't already back I would go in and look too !
So sounds like potentially a good deal ... if DW (Dear wife) likes it, buying from someone you know and can easily go back to for the inevitable questions you will have ... there is a definite learning curve ... maybe not priceless, but definitely valuable.
Remember we're not getting any younger ... other things being equal, enjoy it. ;D
