In 2018, myself and a mate completed the Great North Walk from Sydney to Newcastle. We did 22 legs each of one day over a couple of years.
Anyhow, we had to do a lot of car shuffles. One time we were going down a road and it got too difficult for the cars so we stopped.
I suspect that my Jeep could do it easily. It is safer of course if 2 Jeeps are travelling together.
I am retired, so I am flexible with what ever day suits you.
Let me know
