Towing our camper 910kg fully loaded - thank you free weighbridge on Hume@Tallarook !

Computer claims 10.7l/100 @ 100km/hr - but average speed was a tad under 80km/hr .

No real hard work , just gravelly roads and a bit of up n down .

Car tows really well , only threw one fault ! ( but it might be a biggy .....)

Oh and the remote fob battery went flat ....in an area of no internet or mobile service .
So pack one of those !

Also , dont buy a camper based on price - i know its a consideration but you truly get what you pay for .
There are some bargains in the secondhand market , maybe try to rent a couple prior to laying the cashola down .

Spotted the lights on on the way past on Friday. I so wished I'd seen the lights on early enough to be able to pull in and weigh the car. Have done this a few times now and missed it, they seem to forget to turn it all off.

OK so all these stories I hear of getting 10s, 11,and 12s are just that, stories, only time I got 12l/100ks was when the camper was empty and the D4 was empty on a trip to Gosford and back and it was high 12s.

It's great to be towing at 12 to 13s again, like we were getting in the D2, and having the longrange tank it's great to have that extra range.

Difference driving styles, a guess when it comes to the exact weight you're actually towing, different road conditions, weather conditions(windy not windy) accessories on the car, weight of the car, tyres(bigger more aggresive) believing the on board computer verses actual fill ups, there are so many variables, no two vehicles will ever be the same, exact or not.

Oh yeah and people fudging the numbers

This is going off topic but mine reads 10.6 and measured 12.55. I'd say it's a bit out

You can ONLY calculate from the pump if you know the fuel was the same temperature when delivered and the ambient tank / atmospheric temps were the same as last fill.

And only if the same bowser is used...

The temps were on par but the bowser, doesn't matter really.

Fill to the brim
Reset trip A
Drive 292 ks
Fill to the brim
Calculate

Yeah, I wouldn't trust it..
Air trapped in tank, etc. can cause a huge variation...

I'd much rather trust the computer in my case
