No, but I did change all the radiator hoses (5) on a Gen I recently...same approach. As you know, once you remove wiper arms and cowling, it's still a tight fit. I asked my friendly Tech about same, and he told me that he can do it with this approach MOST of the time...BUT, on occasion, he's had to remove intake manifold to get the thermostat job done !! I guess it can vary Viper to Viper. I'll take a better look later this week when I change the rad. hoses on the other Gen I.
P.S. Sounds like the gang had a GOOD time on the KY trip, Will.
