It would be interesting to see on the scale how tensioning the hitch bars affects weight transfer. Are you running with the bars highly tensioned?
Unhitched front weight 2520# / hitched 2360# so approx 200 pounds are being shifted front to rear - backwards to expectation.
Trailer unhitched weight 5500# / hitched 4560# - or around 1000# tongue
unhitched Front + rear axle 4880# / hitched 5800# - or around 1000# tongue
Unhitched rear 2360# / hitched 3500#= around 1000# tongue + 200# transfer front to rear. So the math (in rough numbers) appears to add up.
What I didn't measure was hitched without weight distribution (like what you said would be interesting). It's $8 a weigh and I felt I've spent enough there.
The bars are cranked nearly in (farther in is more tension) and are rated to 1000#. I can purchase a set of 1400# bars for about $240 but the trailer is level now. More tension would crank the front of the trailer up and overload the rear trailer axle.
Alternately I could use the 2" drop bar (instead of the 4" I used that weekend) and put less pressure in the AirLifts. With the trailer level I would expect more weight transfer rear to front with a lower back end, but like I said, it felt real stable with all that weight on the rear axle and 50 psi in the MT/R's (Load Range D).
I have a set of Michelin XPS Ribs (Load Range E) picked out for the spring and those will be the main tugging / summer tires and I'll save the MT/R's for winter and goofing off.
