What are the 7 most important equipment or gear for an extended overland travel? The answer is not that easy, you have to ask yourself what equipment stuff had been a show-stopper. Or which gear you had really miss if it stop working, because of the comfort it brings with.
These list is extremely individual. It depends on the Area you plan to travel, the weather you will meet, the way how your camp looks like (Ground tent, Rooftop-Tent, Popup Roof, or sleeping inside).
However your overland setup looks like, i guess it may be helpful to see what was important for us, if you don't had that much overland experience. Here is our list in descending order:
