Jacks down to the ground. Chocks on the wheels. Slides in. Awning in.
I leave chocks and jacks down 24x7. I also have the camper facing West - East. The front is facing West. Reason? We get high winds, and 90% of the time they come out of the West blowing East. With the camper front facing West, the front of the camper gets the brunt of the wind, just like when towing on the road. If it is made to withstand 80 mph headwind on the interstate, it surely can endure a 40 mph wind sitting in my driveway, provided the wind is hitting head on.
Now, if the trailer were facing side ways to the wind, it probably would not take 80 mph winds to top it over. Probably a lot less. With jacks down, it creates more points in contact with the ground, causing the camper to be more stable.
About lightning? The chance of your camper getting hit by lightning is probably about as great as your car or truck getting hit. That's why they created that thing called, "insurance."
