Also make sure you make a wide enough turn with the truck so the trailer does not wind up in a ditch.
My turn for a story. This was back in 1986 on Memorial day weekend, we had traveled to Hocking Hills for a weeks vacation and trail riding. All decked out in our brand new Ford dually, towing behind a brand new Lazy N 3 horse slant with a 14' living quarters. We had stayed at a private campground for a few days and wanted to move to the State forest campground for the rest of the week, after the weekenders had left. The rig was quite long and the dirt road has sharp bends. My husband made a right turn a little too close on a hairpin turn and the trailer almost went over the hill!
Out in the middle of nowhere and we could not get anyone on the CB. This was before cell phones or OnStar..lol We manage to dig out the tail gate and get the horses out. There was no way to get to the tack room to get a saddle or bridle, so my husband had to hoof it up to a house about a mile away. A tow truck arrived and he had to hook up to the side and pull the trailer back on the road. It's a good thing that truck held that trailer on the road. Thank goodness for goosenecks. We would have lost everything over that hill.
