Choosing a petrol 4wd is not a mistake, its a personal choice. The cost difference between a petrol and diesel was significant enough for us to choose the petrol as we would never recover the premium price of the diesel when we looked at similar second hand vehicles. Everyone's situation will be different, you will need to do the math to see what works best for you with purchase price difference v expected km's travelled per year and subsequent fuel usage.
We own a V6 petrol D3 and have just returned from one month of touring over 9000km through the outback. We did the red centre, crossed the Simpson, toured SA around Innamincka and Coongie Lakes etc and outback Qld. Like most people, I choose to use premium unleaded when available, but places like Mt Dare only sell regular 91 unleaded. I think Innamincka also only had 91? Everywhere we went unleaded petrol was available. The D3 user manual states to use fuel no lower than RON 90, so you'll be fine. You definitely don't need 98, again that's a personal choice. We crossed the Simpson using 91 and noticed no significant reduced performance (if any at all?), distance was 515km from Mt Dare to Birdsville and used 135 litres. That was the only leg of the entire trip that we used jerry cans.
I'll post a trip review in the next few days after I get a chance to transfer all the photos onto the computer and sort them out.
All the modifications we have done to our D3 can be easily removed and fitted to a D4 when we decide to upgrade when the time arises, saving even more funds in the future.
Plan your trips for the fuel stops, save your money by not trading in for a diesel now, and enjoy the capabilities of your V6 D3 for now.
If you decide to upgrade to a D4 in future years, weigh up the petrol v diesel again and see if you can not only justify the price premium, but also think what other mods can be done to the vehicle with the money saved in the short term by choosing petrol over diesel.
We're already planning Cape York for next year, might see you there!
