I think you'll find most of the older / family folks that own the bigger SUVs don't give a tinker's damn about what 'looks cool'.That's a dope looking and highly capable Tahoe from what it appears!
What I said was more of a generalization, of course. The average "modded" Tahoe does not look like this at all, far from it in fact. This is a very clean build that likely took time an money. It still doesn't have the cool factor that a T4R or a Taco have.
Folks have to keep in mind that there's 4-5 different 'camps' in vehicle camping. A lot of them doing this stuff long before it was re-branded as 'Overlanding' and had a zero or two tacked on all the pricing. These disparate groups are not going to agree on much besides 'go somewhere and explore / camp'
