I use Trucker Path on and off. It's a pig and slows down over time, so I kill it off regularly, never for routing (exit/stop reviews and load.) I like Windy for weather; pulled my cheese out of the fire given I can see wind mapping. Between TSD Open Roads and Gas Buddy, I can usually find a score for diesel. Las Cruces last Monday was that - TSD was SOL, flipped to Gas Buddy and I found a Circle-K with $2.59/gal. Awfully slow, but less pain.
