The Stage 1, with leaf springs and no soundproofing, is likely to have been driven more slowly than a County typically is - and I have found that speed is the main determinant of economy in mine!

ADF planning range for the landie is 450Km from 60l of diesel but thats a mixed dressing of driving and not just a highway run...
550Km is realistic from the GS perenties and IMHO Dobbo from your setup you should be able to get around the 750 Km/100l without the horse float on and accounting for the missing weight of the rust thats fallen out of your chassis. :)
Just returned from a quick trip to Adelaide via Hay, Swan Hill, and SW Victoria and return via the Birdsville track/inside track in my Dfender with the 4BD1T/R380/1.2 TC. Vehicle was fully loaded no roof rack or trailer - cruising at 100-110 Kmh wherever possible - inside track was heavy going on the northern section - Fuel consumption over 5615 kms:
Worst 6.12kms/lt 16.33lts/100km 17.27mpg(northern section of B T)
Best 7.92kms/lt 12.63lts/100km 22.33mpg
Average 7.25kms/ly 13.80lts/100kms 20.44mpg
I trust that this info is of use

PS average for the main part of the track 7.59kms/lt 13.17lts/100kms 21.44mpg
I did 1300km the last long weekend at 150L.....11.53L/100km. That was with roofrack, roof tent, and trying to keep up with a petrol rodeo 100-110kph.Basing fuel use for my big trip at 16L/100km, which I hope I never acheive.
cheers

On the highway my 120" with LT95 and isuzu and 7.50-16 tyres gets 11 to 11.5L/100km at about 105km/h. 2500ish rpm not sure.
Looking at ways to get a bit of wieght out of it at the moment to make it a bit lighter.
Looks like the LT85 does get a bit better economy, about 10-10.5L/100km at 105km/h (1950rpm). I have a specific fuel consumption graph for the 4bd1, that i got of here somewhere, that shows that the lowest specific fuel comsumption is at 1200rpm (full power only was shown). Either side of that there was a slight but steady increase. This trend will remain at lower power setting.
Specific fuel consumption has the units (metric) of grams per kW hr.
im getting 10 to 11 to the 100km
intercooled , 7.50s and a 4 speed
We averaged around 10ltrs per 100 on a camping trip a while ago towing a loaded camper trailer with the back packed and about an hour or so on dirt road with abit of low range work;)
Running an lt95 gbox, 32" muddies and roof racks:)
TIM.
1065 KLM on 126 ltrs from coles. 33" BF speedo reads 105 klmh GPS says 110Klmh roof rack with 2 wheels & tent on top, loaded up for a 4 day camp
i know the Ltrs is about correct becouse i run out
Broke 30mpg on the last few trips.
That's just over 10.6 km/l.
I don't usually get that high, my long term average is around 10.
I get 9.5 -10l/100km consistently. Have seen as low as 8l/100km.
I guess the more streemlined Rangie body helps, But I am turning 35's and am 6" higher than standard. I am also N/A with an LT85
