I know exactly how you feel. I've been fighting myself from looking into a set myself, but I don't think there's a set made for the SRT yet, just the other GC's.
I'm thinking that Jeep felt confident not offering them due to the low chances of damage from sand, salt, etc due to their designing and long term testing results. If you noticed, there's protection film along the lower sides before the rear wheels to prevent chipping. I'm not sure that makes me or anyone else comfortable though!
Even though we've had a mild Winter in Massachusetts so far, there's been some road sanding everywhere. I haven't noticed chipping on the sides yet at 5500 miles. I'm keeping my fingers crossed. If a set of mudflaps become available, I'll see how they look before I decide to get them. Even though it would suck to chip the paint, it might look just as bad with mudflaps on it ruining the sporty lines of the SRT. (JMO)
The highway is the killer. Try to avoid it after lousy weather or drive slower when you do use it.
