I replaced my "Carefree of Colorado" a few years back. The rivets need to be drilled out and replaced with pop rivets when it goes back together. Good advice on research, and the mfg. should have enough to get you started. The torsion springs should be treated with respect, as there is a lot of energy stored in them when they are wound up. The springs are untainted steel, and should be checked if you remove them, as they are not in a dry place. The awning can be replaced without removing the spring.
