Do I need to take a 4WD to the Karajini Area?

No mate, a 4WD is not a necessary. Winnebago, hiace van, what ever !
No worries.

Hi Andrew - I have done the park in my xf falcon towing a trailer about 4 years ago with no problems at all, a few spots are very shaley just take it easy.I did the run again 2 years ago in Patrol and camper trailer and am taking a pommy mate and his wife there in Oct 06 (cant wait) its a lovley part of our country. Take it easy and I cant see the Winabago having any problems, - enjoy your trip

Hi Andrew
You will have no worries, was up there last year and there were lots of cars and vans, we stopped at savannah camping area, no camp fires allowed, and preferred it to Dales camping area, it's a great area enjoy can't wait to get back

Hi Andrew,
Your Winnibago(spelling?) will be fine though look out for some ruts in the roads from this years cyclone season ( wheel arch damage to my camper trailer). Was down there in May this year. Love it every time. Water was a little chilly for swimming but bearable. I here that night time temps are dropping below zero out that way at the moment so RUG UP. Perhaps some Newman or TP residents could shed more light on the temp?
Cheers

Andrew, was there two weeks ago. Roads in are in great nick and no worries taking an R/V or any vehicle for that matter (the number of "wicked" campers are testiment to that!) . Would highly reccomend the "Savannah" campsite as opposed to the Dales Gorge site. Savannah is a tad more expensive but much better as far as the sites are larger, berter spaced and there are solar showers etc. Having had so much rain over the cyclone season, everything is green and there is plenty of water in the gorges. Cheers. Mick.
