We have a Redverz Atacama. Nice and big and tall. But, it packs big too. It’s fine if you ride solo - just strap it to the pillion seat but a bit of a problem if you ride with an actual pillion on the pillion seat. There’s also loads and loads of fabric to deal with that always seems to be covered in condensation when packing it up. Ours is relegated to car camping now.
What do you want a tall tent for? It’s all very well being able to stand upright but everything else is on the floor all the time. You end up crawling or kneeling anyway and unless you still have good balance getting dressed stood up with nothing to hold onto can be amusing, especially to anyone who happens to be with you.
There's always your camping chair for that
