How much $ is to much

Good day All.
Now back at work, after spending 8 weeks heading to Perth, via Eyre peninsula, and back via the SW of WA. From Canberra (Queanbeyan)..
What a fantastic trip, I will try and get around to writing up a blog, when I can.
I just thought I would put some stats up to see what opinions come back at me.
We traveled 10360km
Averaged 13.6L per 100km
Spent $2326.64 on diesel
All up spent about $8500 including fuel
24 nights at various caravan parks powered sites
Rest of the time was unpowered camping, except 4 nights in Perth at families.
So so many beautiful places, just can't describe how many places just took our breath away, as we turned a corner or came over a rise. Unbelievable.
We towed our cub regal off road camper all the way (maybe places we shouldn't have)
With no trouble (only got stuck once... Ahh max tracks.. Phew!)
We did live and eat pretty well, after all we hadn't been on a decent holiday since we have been together and now empty nesters. So we could have done it a lot cheaper if we tried... But hey! Can't spend it when your dead eh!
Just thought if anyone is reading this, who was wondering what it really costs to get out there, here ya go...
Can't wait for the next trip. Cheers Odog
Ps we drove a 150 manual prado.
Pss a big explore oz G'day to Sue and Shaun, hope yr travelling safe, and are both having a ball.. Owen n Sue
