We've got a 4.2 Quecha for when it's 6/7 of us. It's true it doesn't fit onto the bongo but we've also got a quecha base tent which fits well. We have the 2 because we can use the base tent when it's only us.
We looked at the 4.1 Quecha but felt that the 4.2 gives more space and is just the same as putting up the 4.1. In addition, we can sleep in the middle section if we all want to be in the tent instead of the bongo

Good luck with the hunt
