Bryon,

Where are you starting from?

This makes a big difference :+)

If starting point is not of any real significance, but travelling in Springtime obviously is, then I would suggest doing a loop from Perth, going North as far as Monkey Mia and looping back East through the West Australian wildflowers, down to Margaret river (wineries and great surfing) before travelling North again to Perth.

That should be easily achievable in a motorhome and give you a variety of points of interest.

Good luck.

Joe
