I can see alot of you guys have better roads than we have here in Nevada. Just because the map calls it a highway, that doesn't mean squat. I put front and rear straps and one 3 inch wide one around the bottom of the trailer and under each door inside the cab. I cinch it down till I see the suspension squat. Even emergency stops doesn't shift it around on my 14 ft landscape trailer. On overnite and long trips it goes inside the toyhauler pulled by my 2017 Silverado 2500HD 4x4 Duramax diesel.( my wife said it's the last truck before the nursing home, so get what you want) Even with the toy hauler, 26 ft, I still have to check it's still behind me.
