Ok... I was being ummmm short... they are the rancho 9000xl's... I was not aware they had just 9000's without the 'xl'...
I don't like them.... I bought the vx in july and they were already on... they have the in cab controll to charge them and release the air and the dual pressure gauge... they have never worked right... I fill them up, they hold the pressure... I drive around a bit, notice the ride is deteriorating... look down they are empty... one point, one air tube burst... not sure why... but a mech friend found the leak and replaced the tube for me.... worked just like before...! up n down.... I thought it was cool at first... even bragged to buddies how I could go from highway to off-road on-the-fly... but after weeks, nay months now of constantly reaching down and pushing the button to fill them back up every couple hours... now they won't fill up at all anymore... can hear the motor chuggin away but no fill up... and I've had two people including Tone try and find the leak.... no luck... BUT.... I am willing to give them one last chance to redeem themselves.... I'm going to take the vx to a rancho dealer and see if they can find the problem (find it cheap, hope they don't charge to 'find' a problem).... and if it is a reasonable $$ fix, git 'r dun, if they don't hold up... something else goes wrong with them, I'm switching.... I'd rather have something that, in the immortal words of our great denizen of the infomercial Ron Popiel says.... I can: "Set it and Forget it"
