I use 2 2" straps on opposite corners if just going around town, no long distance hauls or highway. If I'm going long distance then I'll use 4 2" straps and make sure it's centered on trailer correctly. If not you will know it when you get on the highway. If you do notice it swaying back and forth, stop and make it right. I have seen people think it will be ok I'm not going far. And the trailer ends up flipping. Just a reminder safety first.
