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 ...

I hear ya. You'd think they'd be strong enough, but I've noticed a couple failures on here over the past year. One was a roll-over, so that's an extreme case. Perhaps the mounts are weak, perhaps some people go Medieval on their tension. I figure if the camper moves in the truck, two of the tie-downs will get tighter. Maybe that's no different than having more tension to begin with. Our camper is about 3,300 pounds and I try to follow the 1/4" rule. I certainly don't break out the micrometers every time I fasten the tie-downs, though. All in all, I guess failures aren't that common.
