On a trip 6 months ago, I had a blowout on our motorhome. I was close to Elk City Ok and they rescued me on the interstate, then installed, on my request, all new tires on my RV very professionally. Today I took my RV to the Oklahoma City T&W shop because the valve stems had been loosening in the extreme cold weather and starting to leak a little air. They took me in when I got there and check each tire and made sure each tire was secure and tighten the valve stems. They were very friendly and then when I went to settle up, they told me it was warranty work and would not charge me anything. I highly recommend this shop because the personnel there were very courteous and professional and they treated me right.
