I use sailboat turn buckles. They are strong, 7,000 lb breaking strength, with fine thread. They are just as fast as fastguns with Torklift tie downs because you can loosen the turnbuckles and then slide out the torklift out of the receiver pretty fast. Then no worries about getting a fastgun stolen or lost, having to buy fastgun locks for each one.
Oh yeah it good to have the spring loaded Torklift receivers in the front. It like a truck valve spring that keeps correct pull and not pull camper apart on rough roads.
