The 500 lbs WAS without weight distribution....in the scenario you put forward (which was good - bully for you that you actually went through the weighing process) your worst case (no tension on bars) left the truck 500 lbs overweight, and then you progressed through the stops to your best case (as far as total weight on the truck) with the Tundra being 300 lbs overweight - you never know what you have until you get it weighed.
You further stated these measurements:
Load truck no trailer:
Fender rt ft 36.25, lt ft 36.25, rt rr 38.5 lt rr 35.5
Inside top of reciever 17.75
Truck and trailer no tension on bars:
Fenders rt ft 37, lt ft 37, rt rr 36, lt rr 36
Reciever 13.75 Bottom of frame ft 13, rr 18.75
Jack 3rd mark
Reciever 15 Bottom of Frame ft 14.75, rr 17.25
Jack 2nd mark:
Reciever 15.2 Bottom of Frame ft 15.75, rr 17.00
Jack 3rd mark
Reciever 15.5 Bottom ofFrame ft 16.0, rr 16.8
Jack at the stop
Fender rt ft 36.25, lt ft 36.25, rt rr 36.75, lt rr 37.00
Reciever 15.75 Bottom of Frame ft 16.25, 16.75
I assume the Bottom of Frame measurements are taken on the trailer - is this correct? It seems to be since the receiver is being brought progressively up as you add tension to the bars, this would push the rear of the trailer down, as you indicate in the last measurement of each sequence.
I also was somewhat confused when I first started taking weights with my current Tow Vehicle/Trailer. I ended up with about eight weighs from each of three separate scales before I was satisfied with the bar setting.
One thing I might suggest -since reweighs are only a buck each - position the axles of the trailer on separate weigh pads with each "experimental" setting of the bar positions. This (getting separate weights on each of the trailer axles) will give you a pretty good idea about how the distribution bars are affecting the weight each of the trailer axles.
Any significant imbalance in the weights on the individual axles will greatly influence trailer stability.
Good luck - please post your subsequent scale results.
