Something stopped working at the campsite?

Pick what is giving you trouble. The app asks the safety question first, then walks you through the checks you can do yourself with no tools, in plain words. If it still needs a tech, it builds a card that tells them exactly what you saw and what you tried, and whether it is safe to keep camping.

• Furnace, air conditioner, fridge, water heater, water and plumbing, tanks and toilet, slides, awning, leveling, generator, power and batteries.
• Display codes and warning lights explained in one sentence, with what you can safely do about them.
• Works with no signal once it has opened on your phone.
• Every step comes from the maker's own manual. Nothing is guessed.
