Absolutely love this app. We often go on extended roadtrips with our trailer and this is definitely a must have app. Lots of excellent camping info, stateparks, wallmarts and lots more. However, I really wish that the road-grade info could be there for ALL the States and Canada. Lots of them have no info on this or are not updated. (Actually no road grades for Canada at all). Would look forward to roadgrades in BC! We drove through Pennsylvania and Virginia today and there were lots of grades missing on the app. 3 weeks ago we drove through W-Virginia and most were missing, although W-Virginia was updated just last week. Wish they would have been on there, so we could have avoided these steep mountains and choose an alternate route. Still.....a wonderful app!
