80 series long range tank

Why did you fit heavy duty springs. My calculation is that even you were carrying 166l (but the 166l tank replaces a smaller tank) extra it's only the weight of a man and a boy and wouldn't justify the harsher ride of heavy duty springs. Overkill I think?

Goran, Thanks comment, I'd agree that ride is a bit harsh, but as well as that extra fuel, you need to add three daughters, gear for their stay at boarding school, clothes for their parents for 3-4 weeks holiday, 2nd spare tyre and few spares and toolbox. Also we don't have the luxury of bitumen, at least for the first 230 clicks of any trip, so it's handy not having the arse of vehicle dragging through every washout. Fitted polyairs recently, could be more overkill. With 2 daughters now away, have fitted Black Widow draw system and cargo barrier, so am still carrying a bit of weight. Catch you later, Regards, Bob.

Bob, that first follow up wasn't writen by me. Someone is playing funny buggers again.

Thanks Coops. You are right. I am in South Hedland. My main concern is that main tank replacement will hang too low under the vehicle. I have 863 OME rear springs and if i replace the sub i will have to go to 864.
With main replacement tank i could stay with my 863 as the weight is mainly in front of the rear axle. What sort of suspension have you got on your 80?

I have King Springs that provided a 3" lift and I'm assuming them to be 864's as I asked for maximum/optimum available. They are coupled with Rancho RS 9000's and I have polyair springs fitted to rear as well. Absolutely no problems at all other than fuel gauge not moving until it has about the same amount of fuel left in it that would have been with original sub tank ie. 50 litres. That's no drama though as it's 900 km's down the road before that happens. I get 1200 -1250 km's from sub-tank and anything up to 750 km's off main (better around town than highway, being local you'd understand the reasons behind that).
