"I'm one who doesn't always remove the fastguns. The jacks can be deployed and lift, especially the rear, a fair amount and all that is happening is you are unloading the camper weight from the truck. There is no additional stress in the fastguns."
Wait a minute, I'm not sure I agree with that. Aren't you essentially stretching the fastguns out no matter what? And in doing so aren't you putting additional torque and stress on the camper frame attachment points??
It seems to me that the fast guns are attached to the truck FRAME not the bed, and by raising the bed or camper, you are stretching them out and pulling much harder.
Maybe I'm seeing this wrong, but I would never raise the camper without releasing the fast guns.
No, Truck and camper rise together as you raise. All that happens is some of the camper weight is shifted from the springs to the jacks and the truck rises with the camper as the truck springs unload - just the opposite of what happens when you drive under the camper and then lower the camper on the truck. As the jacks lower the camper the truck starts to sink as the weight shifts from the jacks to the truck.
You can try it yourself. See what your fast gun setting is (I run 1/2 of the hole before the tension starts). Lower the rear jacks and raise the back end a bit with or without your fast guns. Then check the fast guns. They will still engage at that same point as long as you don't go to far and start trying to raise the truck too.
