Hi! I am really new to Hi-Lo's. Used to camp with a pop-up (a really OLD pop-up). I have been offered a Hi-Lo really, really cheap. It goes up and down and I didn't see any leaks, but it is fairly old - I'd say early 80s. The person showing it to me was not the owner and thus did not know the age. I really like the low profile when towing. I was extremely excited to run across a Hi-Lo that I could afford until I found out the factory is closing. Now I don't know about finding replacement parts. Any thoughts?
