Is there a way to integrate these with the route calculations, so the program can avoid these low points based on the dimensions of the RV the user has entered?
Nice request Ruby. On the surface, if there is NO input for the height of the rig, there probably isn't any means of checking for it during routing at this time.
You might try sending an email to support@undertowsoftware.com and go from there. Keep in mind undertow will NOT just put it in there without Trailer Life's permission, so at best, this needs to be planned, and scheduled for implementation.
