Very spacious. I can stand easily in most of it with a foot to spare. Only has one pocket. I would have preferred more but it's a minor gripe. I haven't had bad weather for it yet so I can't really weigh in on that yet. Hooked up to the Y beautifully but I have to say that with the roof of the Y being swooped so far back it would drain water towards the tent. From the research I did it seems like the best on the market so far. https://www.amazon.com/dp/B07MBJ6R4V?ref=ppx_pop_mob_ap_share

I am not. The tents that are made for vans and suv sit on the ground have an opening for the back hatch. something like this
We went with the same brand but different model. We stayed on mostly dirt and the car would have been a mess without the tent. The size was great. See the Backroadz Tent
A rooftop tent is perfectly fine if you are ok with paying an insane premium for a product that creates drag on the top of your vehicle and also makes your vehicle more top heavy.
Honestly...I would put a rooftop tent on the back of a pickup truck but I would not put it on an SUV. That's just me. Other people do and that's them. Personally, the back of my GC is more than big enough for me to sleep out of with my wife right next to me and I plan to buy a tent that attaches onto the back of my GC but is built on the ground like a regular tent for when I want that kind of thing.

I plan to go with something like THIS only because I can't use a rooftop tent with my wifes disability.
Then I realized you are in a pickup truck, not an SUV. So...nevermind.
Can't speak to the Y, but for the X Napier tents works: https://www.amazon.com/Napier-19100-Backroadz-SUV-Tent/dp/B07MBJ6R4V this is one of them, though the current model is: https://www.amazon.com/Sportz-Blue-Grey-Screen-x7-25-Feet/dp/B004O74Z0G, however, their release schedule implies the new model will be out in a couple months.
I have not used either of these, however, this particular dude did confirm it to work on a Model X, so I see no reason for it not to work on a Model Y.
I've also reached out to the vendor, and they confirmed both variants are compatible with the X, so I see no reason for it not to work on the Y.
That being said, keep in mind that you can't lock the vehicle if the trunk is open, so you'll be sleeping with the vehicle unlocked while the tent is deployed.
