"... My awning got caught flew backwards over the top and caused a huge rip up the side ..."
RV awnings are not designed for windy conditions. You have discovered this in the school of hard knocks. Always retract the awning before you leave and before winds are forecast.
15 mph winds are probably too much. I have a pair of aluminum posts and tie downs to stabilize the free end of the awning. That helps, but I have been reluctant to test them in winds over 15 mph.
"... any suggestions to help with floors, roof, side wall now & it's sitting on my moms property and I'm fixing to move it, any setup info would be greatly appreciated!! ..."
That is a lot of advice with lots of variation. I suggest Internet Search and especially Utube for "how to ...". It may work well to put specific questions in separate new posts. Pictures will be required. Specific "make" and "model" of RV and RV components are recommended for accurate advice. There should be labels on appliances like the awning.
I wish you good luck and happy trails ahead!
