Clif: Thanks for the comment - I see where my last sentence was incorrect and have hopefully corrected it properly , Now, to see if my logic is correct, If we use Jerrod's scale receipts which he graciously provided, above, with his coach attached he had 4680 on the front axle, 8160 on the rear for a total truck weight,(GVW) with trailer hitched, of 12840. When he unhitched and reweighed, he had 4660 on the front axle and 3790 on the rear axle, giving him a GVW at that time of 8440. If my math is correct - 12840 minus 8440 gives a pin weight of 4,400. Back to the receipts - we see that the trailer tires, with the coach hooked up to the truck, were carrying 14780 pounds. Once more assuming my math (which is very rusty these days) is correct, Jerrod had approximately 23 percent of his trailer weight being carried on his pin at the time of this particular weigh-in. Now my use of GVW may be incorrect in this case - I'm simply referring to the total weight of the truck at that point in time.
Now, all this said, I need to go and weigh mine. When I hook up, my truck bed settles a good 2.5 to 3 inches. That was shown on the front end by the low beams blinding on-coming drivers at night (I have adjusted (lowered) them to prevent this which has made them much to low for unloaded night-time driving - sorely need air bags I suppose.) However I digress. If I'm lifting my front end by that much I believe that I must be removing some weight off the front wheels as well. I just need to find out how much. I do have the factory (Ford) fifth-wheel hitch prep and hitch assembly. I keep thinking I need to confirm that the hitch is forward though - on the older hitch there were two ways to install the legs going from the bed to the saddle, one moved the pin location forward a bit more than the other.
Again, my apologies to the OP for hijacking the thread.
