I do something like that except I do it all computerized then print the results. I both an electronic copy and a printed copy. There's a difference or two. Mine is not just about the trips, but about the trailer. Example; I came home from work one evening to find a note taped to my door from somebody wanting to buy my brand new Scamp
. I scanned that note and it has become part of the book. We have a stuffed mascot, and his story is there. Any mods are included.
However you keep the stuff related to your trips and or trailer it always fun to go back through them.
