First of all, I am a newbe so don't assume I know anything, and you will be Correct!
Just purchased a 1977 20' Argosy -- Original manual !
A) Door handle is all original, but the tumblers have a little wear. I was thinking of replacing the entire handle \ lock mechanism. Went to an RV place and he has generics in stock for $50.00 --- and said they were all the same (the ones he had were heavy and appeared to be well built). I though I would replace the whole thing, but reading the post it seems that it is more complicated than that (don't understand why) ---- Are the post trying to keep it original (wasn't my intent) or do the new replacement handles not work !
B) It has aluminum floors (almost sure) -- there is a horizonal high spot close to the furnice --- (not real bad -- didn't even notice it before I bought it). Thought I might buy some of th 1/4 bamboo flooring and install, and thoughts --- sure would hate to have to tear the floor out and put a new one in, but I do want it to be structurally sound.
Thanks guys, know nothing as Schultz would say, but I WILL learn fast.
