Fastgun tiedowns - tension vs camper weight
The manufacturers specify adjusting the tension so the O-ring is 1/4" below the barrel when the tension is applied. No mention of varying the loading depending on the size and weight of the camper ...

The engineering of a fastgun or a chain & turnbuckle isn't such that it stops side to side movement but forward and back. Since there isn't a lot of stretch, it doesn't take much tension to accomplish this. For us boat owners, I compare camper tie downs to our transom straps. Their primary purpose is to stop bouncing or allowing the boat to slide forward on the trailer. "Snug" usually works for all these restraints.
