To me you don't need to build up a jeep up to be an overland I think it is being self contained. We travel long ways in the Oregon back country. To me its about being able to get from point A to B with as little civilization or paved roads as you can. Last summer my Boy and I crossed from the Oregon/ Nevada Border around the trout creek mountains and drove everything from gravel , dirt, two tracks, And at one point I don't think there was a road lol. Took us three days but we did it. To me That's overlanding. This was done in a Jeep Patriot FDII.
When we go this is some of what we carry
High Lift Jack
Two Jerry cans of Gas
Two Full size spares
A tire patch and puncture kit
Full first aid kid
10 gallons of water
and odd parts and belts that may break
ohh and Duck Tape!!!
Ham Radio
We managed the trip with only one flat (Eastern Oregon Lava Rock Roads eat tires) We had such fun managed to hunt a few coyotes along the way and catch a few fish. To me that's overlanding.
you don't have to have a built up rig just be prepared with what rig you have to handle the situations handed to you
