I don't think he OP is looking for concrete advice as much as he's looking for our ideas likes and dislikes. I don't think he needs to agree or accept every word of any post. But he is trying to gain overall insight from actual RV'ers.
I think WRVPO has given good insight as always, But even his thoughts are not necessarily 100% accurate or foolproof. But they do provide valuable real world insight.
The OP is sort of surveying our thoughts to ensure he is understanding the marketplace vs. building his business model around our thoughts.
