How about some discussion, or a YouTube, about overlanding in a stock 4X4? Seems most info is about mod rigs as if to say one can't go overlanding to adventure in a stock vehicle. It seems that the manufacturers of 4X4's wouldn't agree given that they have invested no small amount of effort in R&D and they outfit with suspensions, drives, AT tires (etc) and market specifically claiming that capability. What are the realities of overlanding in a stock 4X4? What are the capabilities and restrictions associated with "stock"? Why do you say that larger tires and lifts are "required"? Does adventure require investments into a modified rig? I'm an old sailor and we had the expression that "paradise looks the same regardless of the size of the cockpit".
I think it depends on
which stock vehicle we are talking about.
Tacoma; in stock format, the TRD models have good ground clearance and generally do not have running boards, and are ready to do some exploring.
4Runner; generally not ready
Silverado; most have running boards, street tires, and are geared for street running and towing
F150; same as the Silverado
Raptor; bring it!
Ram PowerWagon; Bring it!
Subaru; street tires, which are not really ready for rocks and sticks
Jeep; if you want to pay through the nose for a diff locked jeep, then, I suppose it's ready.
Most trucks and SUVs have 31.5" tires, which when aired down really drop the clearance of any vehicle.
Of the more affordable vehicles, I think the Tacoma is the most trail ready
