Tie-Down Brackets

This isn't RV related, but I'm heading to Oshkosh in a couple of weeks and needed some tie-down brackets.  Never one to buy something I can make myself, I picked up some 3/16" sheet steel and u bolts and whipped these puppies up.  They'll be anchored to the ground with 3 12" long spikes shown below driven in at various angles.



Here is the backside of the tie down.  After the sheet steel is painted, the nuts will be fastened with lock-tite and the the bolts will be cut off and peened over to prevent them from ever coming apart.



Here are the finished tie down brackets.



And the backside showing how the bolts are peened over to lock everything together.
