Since getting them from Monaco will prove to be a problem, find a full service sign shop. Chances are they can pull the logo off of one of their sources and make a vinyl replacement as big or as small as you like.
The sign shop that I used got the new Jayco logo off the web, made me four new vinyl logos for my fiver, and made custom script for the name of the rig. Getting the old ones off is a bear, but I have one side done, and the new logo really freshens the look of the rig.
