A GL is not a G-Wagen, not even close.
I often hear things statements, and certainly agree that the two are completely different. That said, in practical terms--stock for stock, or mild-mod for similar mild-mod--what exactly are the enormous differences between the two in everyday life and/or actual off-roading (leaving apart all the discussion around how the G-class is "built to a different standard", or "over engineered", etc., but focusing on actual capability)?
I'd love to see an actual video of equal drivers taking the same exact trails/lines with the two vehicles to truly see where the differences manifest themselves (I've never seen such.)
I suspect that the keyboard off-roading may overstate the differences in capability between the G and GL platforms (not arguing they are the same[I agree the G with it's triple lockers will do better in most situations] just that the difference may not be as big as we like to think in practice, especially for overlanding type travel vs. rock-crawling.)
