Hi All,

Interesting thread on OL for some of you who tow with a 3.9:

'Hi Guys,

I have just returned from a 2,600 km Caravan trip.
We had head winds at some stages, lots of hills and mountain ranges and a few good flat smooth roads.

Most of the time, on good roads, I sat on 100 to 105 kph, pulling the 15' Pop Top Caravan.
Poor roads, 90 to 95kph.

At 2,500 rpm to 2,750 rpm, the Disco pulled the best.
Up hills at 3,400 rpm, it pulled really well.

For the first time since I have had this vehicle, it was easy to drive, pulling a caravan, without having to contantly drop back to third to gain lost speed.
(That normally happened a lot in head wind)

The fuel consumption for the whole trip averaged at 20.5 lt per 100 km. Worst was 22, driving up through Cunninghams Gap, from Brisbane to warwick.
Best 19 travelling on flat roads at 100 kph, with of course, van in tow.
(Previously, 24 was common on head winds and hills, with 19 on the flats)

Overall, I'm very happy with the switch from a Disco geared transfer case to a Defender geared case.
When we get the new Caravan, I'll be most likely sitting on 90-100 kph, which is ideal for this gearing.

BTW, before we left, I did notice that the Disco was slightly better on fuel around town, than before.
I think the Torque lock up at 70 kph instead of 80, may also help.

Cheers,
Ron'
