Checked on the RV a few weeks ago in storage and noticed a big stain on the ground under the engine area on my Jayco / Seneca. Ends up being coolant from the radiator that had a crack in a weld on the radiator. So I call up Robert in service @ Nicholas Chevrolet and tell him what's up, he runs my Vin # and come to find out my warranty ended about a month prior from the factory......

so I mention to Robert that my rig had just been in for service 2 months prior and has only been to storage since then. Robert says to bring it in so they can determine exactly whats wrong and he will see what he can do. They confirm the crack in the radiator and makes a few calls and calls me the next day to tell me the new radiator is on order and I can pick it up the folowing week and it's all covered under warranty!!!!!!!
So do yourself a favor and if your GM needs service take it in to Nicholas Chevrolet and ask for Robert in service. Good guy!!!
