We have just done this route (430km dirt road) towing a 20ft semi offroad van.
Tires down to 30lb all round, average speed 30km/hr. Corrugations really bad .
Result: Drainage plumbing system smashed to pieces. Otherwise all else seems to have held up ok.
Inside the van a cupboard door handle fell off. Rubber suction cups on GPS and rear view monitor useless.
However, no regrets, great experience.

PVC plumbing????
Not an appropriate material for any RV, but cheap so used a lot.
16 years of bush travel in the OKA and have never broken a pipe or pipe fitting.

The 30kmh "average speed" is a meaningless figure because while 30kmh may be the average, for it to be that the max figure has to be far higher. The higher speed will be the cause where the 30 was keeping the flying rocks quiet.

How things change. :)
Between
Coober Pedy and
Oodnadatta in mid June 2019.
Between Coober Pedy and Oodnadatta.
There was light rain. Then there was more and we were stuck in
Oodnadatta for 3 days until it dried out.

G/Day Peter, just noticed your speed and the revs your vehicle was at.
Was that top gear, ?
Cheers Axle.

Yes, 5th (overdrive) which is good for anything over about 70kph on the flat. That speed is a bit more than we typically cruise at, even on the black top.
The old Perkins just ticks along.
Both the speedo and the tacho are pretty accurate. The speedo is infinitely adjustable.
Cheers,

4 cylinder, 4L, Perkins Phaser, turbo charged, 110HP.
I added an intercooler and more recently changed the turbo.
I had it rebuilt at 330,000km when we bought it (because I could) and it is now 550,000km and going
well.
Returns about 17L/100km in "normal" conditions at around 85kph and 6T.
23-26L/100km across the Simpson.
A lot of OKA owners are changing to Cummins 6BT and Alisons. They GO, and don't seem to suffer much if any fuel consumption increases, but the Perkins does us.
Cheers,
Peter

Hi Kevin
I have had a similar experience in the general area, except that our broken water pipe emptied our
water supply ! Luckily we were with friends who helped out for a few days. Have since beefed up the water pipe area and protected it ( was just a link to an outside tap for convenience) . Must admit that I hate bad corrugations and all that goes with it, even though our camper handles it brilliantly ........ no dust !!
Those SA rocks are pretty darned savage !!
Cheers
Jim

30 PSI in bad corrugations is too high. 20 PSI at 20 kph might gave been better.
That's what we did with horrendous corries in
Rudall River NP with no damage.

My thoughts exactly. 30 PSI is for good dirt.

If corrugations are bad then I’d have dropped tyre pressures lower then 30psi myself also.

Good dirt, don't drop pressures at all. Good for normal hwy speeds.
Washouts, rocks and small corrugations...normal pressures and slow down...40 to 70 k/ph.
Bad corrugations, bigger rocks, low speed 4wd stuff, sandy areas, and no speeds above 70, then lower pressures !!

As noted, how things change - this route in 2019 was a freeway!
