You nailed it. Once they have invested in that lifted overland rig they need constant ego stroking to convince everyone what they have is better.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?
In reality the factory has a much biggr research and development budget than any after market manufacturer. In reality it is all hype. I've been doing it for 40 years. Modified rigs might excel at specific tasks for a defined period of time until something breaks. Completely stock most vehicles are far more reliable and reliability for an overlander should be the rule, not the exception. Guys who mod their rigs and post their adventures on youtube are looking for confirmation they are geniuses. It is all about ego. There are many more overlanders doing far more ambitious adventures in stock vehicles and not wasting time on youtube documentation.
The reality of overlanding in a stock 4x4.... You will go farther on a gallon of gas. I changed from 33x10.50s to 7.50R16s and went from 17mpg to 22mpg. That one change added 95 miles to the range of my TJR. With stock springs and tires the ride will be much smoother. Yes you will be more comfortable but that ride also means less mechanical stress on the vehicle. And all those dollars saved can be spent on adventure.
There are more restrictions on modified rigs than stock rigs.
Adventure just requires curiosity.
