I have the Yakima Load Warrior on my 2000 Runner which is just the smaller version of the Mega Warrior. Ran it thru the car wash yesterday..... no problems.... however I have upgraded the mounting brackets to "Ubolts" to a more secure structure to carry my 33 MT and Hi Lift.....
i got through the car wash once every week or two with mine on and no problems various carwashes, basically any carwash that my height will allow 7'3 seems to be as low as i want to go.
get a silver or white truck, shows less scratches ;-) lolj/k
