What kind of apps and websites are you using when traveling? Any tips for a modern traveler to save time and money while on the road.
GasBuddy for cheap fuel
CalTopo (site, not app) with snotel overlays for snow depths and terrain/slope overlays
Avalanche Forecast for ... well, avalanche forecasts
DOT websites bookmarked for the states I'm travelling through for road closures
I also keep copies of parts fiches, owners/service manuals, wiring diagrams, etc for my vehicles on my phone. Not ideal, but in a pinch it's nice to have that information available.
USB-OTG adapter's kinda handy too.
