I am a member of the club. My DW died unexpectedly last year. So I would offer these thoughts. I think it is good you are looking forward as to what you want to do next.
I would say this, don't listen to closely to those who have never lost a spouse, no matter how well intentioned they don't really get it.
For me, selling the MH was a very hard thing. I unloaded it and sold it by myself. I do not recommend that, as it was very painful. Looking back I would have put it on consignment, or at least had a friend or family member help. Way to many memories, way to much pain
I think first order of business is get the class A sold. Then take a breath, look into your heart and let a few months pass. You will have a better idea of what you want to do.
I have no advise on that. For me I decided, no motorhome for a few years. But each individual is different
I wish you the best, hang in there, it does get better with time
