I had the same issue with the awning on my Wildcat. I asked my dealer about it and he said the awnings don't work as described in the manual anymore. Like you, I wasn't satisfied with that,
I found that if I pull my battery disconnect switch that power to the awning is removed and that works well as long as we don't want to run the fridge while going down the road. However, we quite often do run the fridge while going down the road so, now I just pull the DC fuse for the awning whenever I roll it in for travel.
I also added a travel lock to the awning so that it can't unfurl even if the roller tube holding mechanism gives way which would allow the awning to unroll even without the power applied.
