Jbres,
Probably the best thing you can do is to weigh your rig ready to camp. There will be a slight difference when returning, but from what I understand, unless your bed is loaded with 3 weeks of firewood, there usually isn't much of a difference weight wise to make the w.d. bar adjustment off.
Weigh 3 times:
Truck only- loaded with all family members and normal cargo
Truck & trailer- w.d. bars "unhooked"
Truck & trailer- w.d. bars under tension ("hooked up")
This will tell you how much weight you are transferring back to the front axle (fa) with the w.d. bars under tension. Not sure if you have the '07 "classic" or if it's the '07-'14 body. In your owners manual it should state how much weight should be returned to the fa when the w.d. bars are hooked up compared to truck only fa weight. Generally it is anywhere from restoring 50% of the weight lost up to 100% of the weight. I think our '13 manual stated to return 50% of the weight back to the fa if I remember correctly. I didn't have time to get to the scales yet, probably will wait now until next season since we are done for the year!
Example: Truck only fa weight 3500lbs. Trailer hooked up no w.d. bars- fa weighs 3200lbs. You will want to adjust the w.d. bar tension to return between 150-300lbs back to the fa depending on what the manual states.
Do a search for cat scales and looks for one near you. Take a broom handle or use your bar for your snap up brackets to reach the call button!
Hope this helps!
Chris
