GPS for steep grades

Are there any units or phone apps that will warn us when we are approaching a steep grade? Would love to hear something like, “7% grade 5 miles ahead”. We will be traveling from Maryland to Oakland and back again this April and May. The plan is to unhook the toad and drive each unit separately up or down steep grades. None of the road atlases we have seen seem to give a good definition of what grades are where, we have heard that there are apps and systems that will do that.

Any help pointing us towards the products we should consider would be appreciated.

Thanks

Ok, I will be the first to ask.... Why would you drive the toad and rig separately on hills?

My Garmin RV760 tells me when approaching steep grades. I also use The Mountain Directory (PDF version - East and West) for trip planning. Personally, I think the GPS warning a mile ahead of time is too late.
