trying to date a Hi-Lo
 

Hi! I am looking to purchase an old Hi-Lo. The owners are still looking for the title. However, they were insistent that I know it has an all aluminum frame. Does anyone know when they first started doing that? Might help me date the camper. Thanks!

Look for a tag or sticker on the outside of the trailer, it should have some indication of the model number and the date of manufacture.
