The reason I was seeking an alternate route was because the mighty Duramax threw a P087 code on the way here in late July. This code is typically thrown when towing in hot weather and climbing, and could be caused by a few things. I've taken a stab at resolving it with replacement of the fuel pressure relief valve, but won't know if that works until I am towing again in hot weather and climbing. I didn't want to experiment so far from home. I worked around the code and got here ok. Was looking for a flatter route home.
Thanks,
Mike
