Not sure who told you washboard roads are from the original dozer tracks that pioneered in a road, but that couldn't be further from the truth. Makes no difference rough is rough, but it's just a function of vehicles suspension loading and unloading and drive tires.

Washboard dirt road surface comes from the physics of powered rotating round things pushing vehicles along on that loose surface over time - probably at too-fast rates.

It doesn't take an Australian RV or an expedition RV to travel on extreme washboard.

We take our 24 foot E450 Class C on extremely rutted roads whenever needed boondock camping and rock hounding. What you merely have to do is GO SLOW to keep the RV from coming apart. We have traveled up to 25 miles each way at 7-10 MPH on nasty washboard desert roads. It can be done safely and reliably - but you must have patience - and be willing to have pickup trucks blast past you at 40+ MPH tying to touch only the tops of the ruts ... a trick that will not work with an RV.

25Miles? Try 100 miles. No 7-10 mph is far from practical.:S It would take you years to drive across Western Australia at that speed. Inexperience like that would kill you in outback WA, people have died. Most do washboard at 30-40mph or faster in this case 55mph. People have come from the US and other countries and have died on these tracks.Something you would be warned about driving on very rough roads in extreme Outback Australia:R
