In 27 years of RVing, I have needed a tow one time (I fix my own flats).
That puts me ahead thousands of dollars to the point that even if I need another tow someday, I'm still money ahead.
Also, when I got that tow I didn't have to fool around with some company trying to save a buck. A tow company was called and they showed up fast.
That, in my mind, is better service than having RA.
