I realize there isn't a lot of actual "reality" in reality TV but my wife and I happened to catch a marathon of some show where they followed people who were looking to purchase a new RV.
They pretty much all follow the same formula. They give a budget and a list of "must-haves" and the salesman shows them exactly 3 RVs. Each one has pros and cons and then at the end of the show, they pick the one they like best.
After watching 4 or 5 shows in a row, I was pretty amazed at how often the salesman could find an RV within a few thousand dollars of their budget. One couple wanted an RV for around $100,000. So that's what they showed. Another couple wanted one for around $225,000. So that's what they got. I honestly couldn't tell the difference between the cheaper ones and the more expensive ones. Although a couple of the more expensive ones didn't even have LED lighting.
I thought a few times they really had to reach to find a problem with them. One lady didn't like the feel of the carpet. Another didn't like the way the drawer handles looked. One didn't like the way the couch folded out.
Having gone through it a few times myself just makes me notice how horribly fake the show is. They usually show the people a few months down the road with the RV they purchased so apparently they were able to live with the "cons" of that particular one.
Somehow we were lucky enough to buy one that doesn't have anything we don't like about it.
