Looking for an affordable, small rv gift? Why not a compass? Determining direction isn't just for hikers, though rvers who hike around a lot will get a lot of use from it. But for us, it is a simple fact that we move from place to place, get turned around and half the time have no clue where we are going or which direction the rv is facing!
A compass makes a great rv gift because it is small and will be used, guaranteed (oh...unless the rvers never move the motorhome or travel trailer...then not so much).
Also, in unfamiliar territory in the middle of nowhere, instead of flipping a coin to go right or left, they can pull out the compass (or flip it, but not recommended!).
Anyway...it is a cute gift idea. If unsure, why not go with something like a compass keychain for the rv keys - like 2 rv gifts in one!
