More on putting eyelets in the side corners of the roof. I drilled all the way thru the side wall and mounted my one inch eyelet on the outside. I also use large washers on both sides of the roof side. On the inside I added another 0ne inch eyelet that would screw into the outside eyelet long shaft bolt. This inside eyelet will also keep the top from moving from side to side with a cris cross 1/2-inch ratchet web strap going down crisscross one of the tent beds entrance..
We also like to throw up a 20X30 special tarp over out whole trailer sometimes especially when camping in a heavy wooded area where trees will drop water for days after rain storms. ELKMONT in the smoky mtns does this and everyone has a tarp over their tents and trailer there. The 20X30 tarp has holes cutout in it to go around the roof mounted a/c and venets as well as a couple of roof mounted two way radio antennas. The back of the tarp goes straight to the ground at an angle. gives me another good spot to stack firewood. The front part of the tarp comes out over both tent ends and the trailer roof and the extended awning. Then I put up four COLEMAN tent poles (WALLMART) to make the whole front even with the awning height. Then these four location tie off the the ground using 1/2-inch ratchet web straps with the two outside straps going to the the earth augers shown above. Using the 1/2-inch ratchet web starps allow all of this to come down in a hurry if need to because of storms. Click Click and it is all down. Using rope cords you end up cutting the rope when in a hurry.
I never had any luck using the small wire type screw in ground anchors. I use the 15-inch long Earth Ground 3-inch Ancors. These screw into the ground with minimum effort just using a large screwdriver slipped thru the eyelet.. Does not disturb the ground when you unscrew it. These guy really hold up good alot of wind.
Works good for us at any rate....
sample photos from GOOGLE images NOTE I don't use the rope shown above - was part of the photo....
This also shows how I adapted to get the inside eyelet mounted. all hardware 1/4-20 stainless steel LOWES. I keep my 1/2-inch ratchet web straps hooked into the eyelets across the bed entrance when not being use. This adds even more structure pull to sides of the roof and is all hidden behind the curtain valance we have around the whole inside of the trailer.
Been thru some pretty strong winds using this setup without any problems.
