While there are many differences in what the term "Overlanding" means, multi-year or full-time does tend to mean the same for those that do it. No matter one's experience level when setting off on a very long overlanding journey we all end up being much more conservative in our route choices. Our initial fantastical imagination, many times, results in an overbuilt rig for what it will be subjected to. I don't watch many overland YouTube channels because they are more deceit than truth. One particular episode from a channel that does a decent job happens to capture the raw essence of the difference when full-time overlanding. If you don't want to watch the entire thing just listen to Kelsey from 22:20.
