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.
