Breakdown Information

Just returned from a 3 week trip down to quartzsite, and slab city. all went well till on the way home to Santa Cruz Ca. I pulled into a rest area on I10 and at the same time my throttle cable and my shifter cable both gave up the ghost. what are the odds of that happening?/? I called good sam and was told that they couldn't send anyone till the next day ( monday) They send out a mechanic who assessed the problem and charged me 90 bucks the that info. and tried to get me to pay for his trip back to his shop. after another call to good sam, they told them that they would be paying for that trip. then 5 hours later a tow truck shows up and after about 3 hours of getting ready we finally took off to Colton Truck where they hadn't recieved any call from Good sam that we were coming. By wed, they told me that Freightliner told them that they didn't make those cables anymore??? I had to have them made 550.00, by friday I was on the road again after a bill of 11oo.00, only to have the new throttle cable to sieze up just as I was getting close to home. This has not been one of my better trips.
