I drive a Suburban as a work truck (civil engineer) and it’s great. I keep tons of equipment in it, plus still have enough room to lay down and sleep in back when I have to be on a jobsite for extended periods. Fantastic vehicle.
They’re really nothing near as cumbersome or hard to drive as people here, most of whom have never driven one, would have you believe. That whole thing is a myth.
Im not familiar with the next generation Suburban with independent rear suspension, but for most purposes I can’t really imagine it’s going to be all that different except for maybe feeling a little more planted when cornering aggressively. Also, it offers a diesel option, which might be worth looking at.
Mileage isn’t bad considering the size of the vehicle. By weight, it’s literally EXACTLY as efficient as a typical compact hybrid SUV. A 3500lb RAV4 hybrid gets about 40mpg hwy. A 7000lb Suburban gets about 20mpg hwy. But I can’t use a RAV4, and I need a Suburban.
If you want/need one, get it. Don’t be dissuaded by people who don’t have clue what they’re talking about.
