Like others, I recommend looking at the suburban platform. I would avoid the tahoe versions. While I understand the quality risk, I do wonder if the issues get amplified. BTW I drive one and have for 40 yrs so I'm a fan.. You could also consider a Toyota Sienna 4x4 and lift it at some point. It does only have a 3500 lb tow limit, and I imagine it would be limited with 8 people in the vehicle, loaded down, and towing a trailer.
