G'Day all, We have a Kedron off road van tipping the scales at 3.5 t and using a 79 series turbo ute as a tug. It does a pretty good job dragging this thing around but it is at it's limit in hilly country. It can climb the
Toowoomba range in 2nd gear easily but the decent is a different story. In 1st gear you still have to use the brakes seven or eight times a minute to hold her under 3000 revs. It can take 10-15 minutes to get to the bottom depending on the number of trucks and relying on brakes is not a good idea.
I was wondering how a 3-4t 4x4 short wheelbase cab-over truck would go as a tug, should have enough grunt as
well as an exhaust brake to fight gravity on long decents. Not sure about rough corrugated roads. Would appreciate any comment.
Regards Bill.

Hi Bill
I'd be hanging on to my 79 series, it's the best thing Toyota made since the shorty, I've got one & have had it for 7 years and keep getting told not to even think about the new V8's, besides how often are you going to do the
Toowoomba range anyway.
Cheers

I wouldn't think it would be worth contemplating changing for the same reason Rick said.
How many times will you be going down hills like the
Toowoomba Range?
The exhaust brakes on most of the smaller type trucks isn't as good as the bigger engined trucks either. They work better at higher revs than the Jake brakes.
Compare the size and manoeuvrability of the small truck 4x4 to the general versatility of your 79, I know which one I would prefer.
And the ride quality would be better in the 79 in all circumstances.
I would be surprised if the 3 - 4 ton 4x4 would be very much quicker up the Range than the 79.
General running costs would also be in the 79's favour, as
well as availability of parts.

G/day,Bill If the brakes on the Kedron are doing their job all you should be stopping is the 79,maybe you should look at this first.

Ditto to the brakes on the van but with the front hubs Unlocked you can use low 2nd and it will engine brake better, same going up
hill.

Have you thought about exhaust brakes for your 79? If I remember right they cost in the vicinity of $1100 but it has been a while since I done homework on them so I may be a little out of touch with the price.
Sounds like you have an enviable unit now and I would be looking to keep what you have and modify that to suit your exact needs.

That's what I was going to say - there are a few mobs that fit exhaust brakes to diesel 4WD's so if slowing the rig on a long descent is your only gripe with the 79-Series, why not just fit an exhaust brake?

Hi Bill,
May have a similar problem early next year when we get our Kedron. We have a 100series TD with chip & 3" exhaust, so hoping it will do the job. I have done a mod to the transmission by removing the auto centre diff lock wire from the transmission controller so that we can now use low range on the bitumen which hopefully should assist with the type of issues you are facing. I got all the details of how etc from the LCOOL website. Dont know if this is possible with your vehicle, but just thought I would mention it.
Regards
Chris

One small point to watch when buying a really heavy van.
Whilst the 100 is rated to tow 3500kg the GCVM is 6680kg
Its GVM is 3260 so cant quite legally tow 3500kg.

His is part time 4wd and as such only needs to have the front hubs unlocked.
Where as us with the full time 4wds and automatic locking centre diff need the seven pin mod to do the same.

Graham H - You make a very good and important safety point here. The towing capacity, GVM and GCVM are very much misunderstood.
A lot of the heavier van manufacturers become very defensive when asked what type of vehicles their caravan can be legally towed with to stay within the legal limits of the towing vehicle.

Hi Bill
Some VERY good advice above, and I agree with 90% of it.
We have 79 series turbo at 3.7t mass (have motor reg approval with ARB springs and shocks mod) and 3 t van.
This puts us at 6.7t on the road and care needed at steep and especially long steep descents. My experience is - best engine braking BELOW 1800 RPM as over this it tends to "run on" a bit with less retaration felt and this forces harder braking.
Look to brake balance ie van settings to assist effective control and even distribution of braking effort.
Suggest you consider also:
1 stop at top of long descents to allow all brakes to start descent cool
2 keep engine revs below 1800 to maximise engine braking (trade off here as this takes longer to get to the bottom but engine won't overheat and you could ahve significantly less actual braking)
3 use low range 4th with HUBS FREE if you want better engine braking (at times this seems to be the best as I use this on steep hills with truck only ie in
Flinders Ranges - Skytrek track etc)
Personally I would not buy the truck as you would IMHO face the same issues. If you decide to look seriously at a truck hire one and go for a drive first is my advice.
Just my thoughts.
Cheers Baz

The answer is simple
If you want to keep the car, get a lighter van.
If you want to keep the van, get a bigger tow vehicle.
I have a more simplistic view of travel & can't quite get my head around what the big deal is with having the heaviest van in the
park anyway.
I saw another post where a bloke wanted to know the maximum weight van he could tow behind a patrol.
I would tend to be looking for the lightest van that would suit my needs. I think that is far more practical.
I have owned a van & found I preferred the ease & freedom of
camping & have reverted back to that.

I wish I had asked what was the heaviest van i could tow with a Patrol.
Then I wouldnt have bought the one I did and then have to spend $23,000 to buy a Croozer.
Maybe he wanted to know so as to stay below it and not to see how big and heavy he could go
As the man says its not necessarliy the best but the best for the Job that he wants and looking at some of the lighter built ones he may
well be the sensible one.

Great vehicle, keep her as others have said.
Good to see you are concerned about not having complete control with engine breaking.
As others have said, low range with your hubs unlocked or a exhaust brake will fix all.
Have a safe one

Thanks for all the replies, some good advice and food for thought. It's not that we wanted the heavist van in the park, far from it. We needed a van big enough to live in (not just for holidays) and bulletproof for all road conditions, not just bitumen. To get that you need to get away from chipboard, staples and glue and unfortunatly that means weight.
The van brakes are 12" commercial electric and work very
well but I don't like using brakes on long or steep decents. Once again I appreciate all the
feedback and thank you.
Regards Bill.

Perhaps a combination of both is best and have the van brakes set up to come on just before the tug.
Nothing worse than a heavy van pushing you around and downhill at that.

"To get that you need to get away from chipboard, staples and glue and unfortunatly that means weight." that is not true. they are poorly designed and not engineered. Any dumb fool can throw together heavy and strong, but takes intelligence and engineering design to make light and strong. brute force and ignorance is the norm for RV industry in Aus
3.5t behind a Cruiser will never be safe. Under new scheme starting 01/01/2010 vans and m/h will be weighed roadside or convenient public weigh station Watch for public details release

Is that like a racing yacht,
If it doesn't break it's too heavy and if it does break it's too light.

Hi Bill,
Tow vehicle is always a debate but less so on a Kedron. If you have a Kedron and want to use it in the outback, you are almost limited to a cruiser. The problem is backup in the middle of nowhere.
Try and find the F250, GMC and Iveco dealer in Cooper Pedy. I know that the point people raise about Kedrons are reaching the landcruisers tow capacity but 90% are towed by landcruisers. My Kedron is overweight for the landcruiser (200TD) but you have little choice at the end of the day.
What were you looking at Hino, Iveco etc?
Carl

Hope your insurance company isnt reading this then.
They get rigs weighed nowadays as they know that a lot are overweight
If so bye bye claim
