RV Service Center near Cedar City Utah

I need to take my rig in to have the atwood leveling legs system replaced with a new Hydraulic system and I'm traveling along way from home, we were planning on traveling through Bryce,Zion ect the month of Sept/Oct and i need to find a dealership that has time and is in close proximity to get that done. I haven't been very successful in finding a place and am hoping you might have some ideas? thanks in advance for any help you can provide
