David,
Yes, SOTAmaps has a powerful Road Route tool to identify SOTA summits within a defined corridor along a road route. Got to the SOTAmapping website then choose Mapping>Range Mapping from the drop down menus. Click on the Road Route button, identify your start/end cities and the corridor width. Then choose between various road routes and click on map. You can then download the Chosen Summits Listing. Very powerful planning tool!
Good luck on your trip! Guy/n7un
