I went in for an oil change and lube job, came out with an observation from their mechanic of a faulty steering linkage (or what ever it is called) that could fail on my RV. Knowing I plan another trip to Arizona's chuck holed interstate highways, as you might know at 70 mph and if you hit one of their holes eventually damage is only enviable; with Henderson's observant mechanic I feel I have been saved of an eventual failure at possibly an in opportune time. I now feel confident my oil has been changed, joints lubed, and attention to defective parts have been done. I am ready for my next trip. Thanks to Henderson's Line-Up Brake and RV.
