[Fulltiming]

Bill, I haven't yet found a way to get all of those on one device but it may be getting close. I use VMSpc to provide the engine data and Streets and Trips for directions and nearby points of interest. The VMSpc and Streets and trips are both displayed side by side on a laptop on my center console. In front of me suspended from the overhead I have a Garmin Dezl 760 which provides navigation, including the closest truck stops and rest stops, and it will display grade information which I believe is calculated based on its GPS information so I am not sure how accurate it is (altitude is the least accurate of the coordinates for GPS). By using Garmin's app (Smartphone Link) on my Android phone the 760 will display weather information including radar centered on your current location. The Smartphone Link app is free but I believe the weather radar was a one-time $9.95 charge.

I have an app (GPS Status) on my phone that displays direction of travel, pitch and roll and acceleration (in g's) which helps with the 'how smoothly am I driving" question. The direction of the wind in relation to my coach is something I haven't found an app for yet. The phone app from Weather Underground shows the wind direction, speed and gust information for close by weather monitoring stations but it doesn't correlate that with your direction of travel. That one is particularly tricky since terrain can have such tremendous affect on wind speed and direction. I think that sensitive instrumentation mounted on your vehicle would be needed to really be meaningful for direction and strength of wind relative to direction of travel.
