Lee, you are just having to much fun out there in California.
If you have the manual pull down Carefree it may be this one:
http://www.carefreeofcolorado.com/do...e%20Manual.pdf
They show using vice grips to set the tension, but that requires removing the arm from the awning tube - and there is another way I think. Use the arm itself and wind it.
To do that, put the awning down, use a step ladder to set the forward most end on, remove the brace arm that slides inside the awning arm, then remove the awning arm from the coach at the bottom. The ladder should now be supporting the awning on one end. it will want to move toward the coach so you will need to have it tied or held in some way so it can't. Now you wind the arm. With the arm hanging down toward the ground it should be obvious which way it wants to unwind, so wind it the opposite direction to increase the tension. Put everything back like it was and check to see if you are satisfied with the tension. There is a spring in each end so you may also need to wind the opposite end the same amount.
If the awning in the link does not look like yours let me know.
Good luck,
