More on dust

The Toyota ones on Landcruiser and Prado certainly work. They deflect air over the back window to stop some of the vacum effect on the back window. They also help reduce some of the dust entering the vehicle if you leave your air on recirculate by mistake. You will still get dust in and on the rear window but not nearly as much as without.We have so little time to enjoy our land

yea they also get good wraps on patrol list on the GU's.

All vehicles create wake turbulance as they travel along. The idea of the deflector is to improve air flow over the back of the vehicle and increase the amount of attached (laminar) ai flow on the rear window/door area. The increased air flow should result in less dust on the window! How good they are depends on the design(ie how much cash the manufacturer put into wind tunnel testing!!)

The improved airflow is infact an aerodynamic improvement however don't expect any noticable performance gain to your 2 ton rig!!!!

Just completed a trip along the Great Central Road and Mereenie loop in a '92 Nissan Patrol and had no problems with dust. Considered purchasing a deflector before we went, but now I'm glad that we didn't. Dust problems in earlier models seem to have been rectified.

I have a deflector on my GU...
Does not entirely eliminate dust on rear windows, but certainly less with it than without...
Also noticeably reduces the grime buildup on rear of vehicle when driving on wet roads after rain...
Wouldn't be without it!

Thank you for the info. Appreciate it all.

Verdict - Once deflector coming up.

That was quick.

Mine would be a trropie, and knowing Toyota prices.......!
