Chris...you are posting a zillion questions over several threads asking ….I don't know what.
You are searching...for something....in an RV....with "something" as a TV.
I feel for your situation with the recent divorce. I TRULY want to help you but don't know that I , or anyone on the forum, can. With every post the target changes, the parameters change...
There is so much info on the internet that the majority of your questions can be answered with your own research.
Jayco vs Keystone? That is a subjective question. I've looked at lots of both but that can't tell you what you like. Complaints about RV brands? It's never ending on ALL brands. In the price line of trailers you are looking at there is no "gold" brand and in fact involves all brands and types of RVs.
Airstream???
You're worried about having "space" in the RV, why in the world would you even think of an Airstream? A shiny, silver, cramped tunnel?? To each their own.
And no, this is not a "hate filled" post. Just observations based on your questions.
