If your friend or family member is a full time rver, remember that they probably won't have a big tree to display it on. We have a few ornaments we simply hang up in the motorhome...you don't need a tree just to call it an ornament! So even if there isn't a Christmas tree, it can still be displayed every year. It is a nice and small gift, easily stored away.
