I hoping if there is a fellow member who can recommend a app that will give a daily and total trip cost including fuel consumptio, Im not too good at building my own spreadshee.
Fuel map allows record keeping but may not give daily data. Wikicamps trip planner has fuel consumption linked to trip legs but you need to provide your own economy figures before it can be calculated and if course plan each leg. FWIW I've worked with technology almost my entire life. All I do is take a photo of the bowser or receipt, a photo of my odometer and transcribe the relevant few numbers into a notepad at my leisure. Why overly complicate life ?
Layout what you want on a piece of paper. It is basically adding columns, or one box divided by another then often repeated below. Just start simply, you can add further data later.
