How tight did he have them? Even slightly tight I can't move them. This is pretty tight with the cordless impact. I can move them closer to the cross frame. Our Lund has cross channels so it can't move side to side on the trailer plus a rear hold down strap along with the front strap and a channel that fits in the front roller and it's hold down. Our last trailer had three sets of rollers, we could crank the boat basically on dry. Just the axle shifted and was basically waisted. Our new Caravan trailer needs to be deep enough to get on and off with the carpet on the bottom, it adds friction, helps it from moving around especially once dry.
