What travel trailers have theater seats with tray like Jayco has

[PopBeavers]

I am shopping for a travel trailer with theater seats. I really like the seats in the Jayco's I have seen because I like the tray that attaches to the seat and pivots. I have not seen these in any other brand of travel trailer. Are these only found in Jayco trailers or have I just not encountered one yet? Is there a reason I should avoid these seats with trays?

The trays are great. I use one for my computer and the other for dining. One problem: the arms can be flimsy and lean therefore the tray leans. Not good for balancing meal plates. I have propped the arms with bean bags against the wall and works great now.
