best travel crate recommendations? durable + reliable + comfortable

Looking for recommendations for the best travel/collapsible/durable crate for my large breed puppy.

Context: My 4 month old puppy is going to be staying at my parents (her grandparents lol) house for 5 days while I travel for work.

Puppy is already about 25-26 lbs and is going to be a big dog, so we have an XL crate at home with a divider that we use through the night right now. This crate DOES NOT fit in my car. I drive a mid-size SUV and there's no way to get it in my car unless we fully take it apart and then reassemble which I don't want to do every time we take her to stay somewhere.

Instead, I'm looking for a durable and comfortable travel crate that I can have in my car and bring to my parents for short trips like this. She does pretty well in the crate, especially overnight, but I need something that's decent sized and not just going to fall over if she puts any weight into it.

Also, if you have any recommendations for helping her keep her routine while at grandparents house I welcome them! They have an older pup that she can play with, but I want to make sure she's still sleeping and has time to decompress.

Thanks in advance!!
