Windsor Rapid (Can it take it?)

I own a Jayco Flamingo windup van which we use extensively. We use it for camping over 70% of the time and the rest in a van park.
We towed it through out back Queensland and South Australia with our 4WD. As you all know the roads can be quite rough and demanding. We have never had any failures or misshaps with the van. It has always held up quite well.

Now we want to go to the next step and get a Windsor Rapid or Jayco Expanda.(Or anything else that can fit a family).
I really like the bed system on the Rapid but want to know for your experiences if the Wooden frame of the Rapid can handle this sort of treatment.

Thankyou.
