Stuck in Kansas!

Got mz Mac (my RV) all checked out in Missouri to make sure everything was good for crossing the rockies…  Got to Hays KS and the "check engine" comes on - I have a scan gauge and it told me the code was for the EGR cooler, which has to do with the emissions system…. and of course it was Sunday and nothing open!  So Theo and I relaxed in the WalMart parking lot waiting for the Dodge dealership to open today.  Turns out they do not have a Sprinter technician.  ah well… So I'm on hold with Chrysler customer support hoping they can find me a dealership…stay tuned.  Glad I filled my fresh water tank yesterday - I was ready for a shower this morning!
