My understanding is that some of the awnings have 2 poles/centers, and some have 3. My new Baja has 3 poles. And yes, the instructions kinda suck. The way mine went up is: 1. install 2 poles across the end with a center connector. Basically that was 2 4' poles with holes in the end, and a center connector with a hole. 2. put together the legs. (mine had 3) a base pole with a little loop for a stake, and an insertable post with a ring on the end. 3. a spring loaded spreader with a cane rubber on one end and a peg on the other is placed on the camper wall, (I placed mine "in" the awning bag), the pin/peg is placed through the ring on the leg and into the hole at the end of the pole that is in the sleeve of the awning.
Two people would make it easier to do, but I did it myself. Sorry I don't have any pics to show. I read the camper manual and the sheet that came with the awning.
Hope it helps!
