Great information and IMO well worth the CAT scale time investment!
Your CAT weights tell us (if my math is correct):
a) TV Gross weight w/TT (3,440 + 4,240) = 7,680lbs
b) TV Gross weight w/TT 7,680 - TV GVWR 7,560 = 120lbs (over GVWR)
c) TV Steer alone 3,600 - TV Steer Axle w/TT 3,440 = 160lbs (delta)
d) Gross TT weight (15,360 - 6,880) = 8,480lbs
e) TT loaded tongue weight (3,200 + 4,580) - (6,880) = 900lbs
CAT Summary:
Present set-up is 120lbs over TV's GVWR ..., may not be a deal breaker but good to know should your loading habits change and/or present loaded tongue weight increase.
Ideal loaded tongue weight range for a 34ft long TT is 13% to 15% of gross weight...., so at 8,480lbs = 1,102lbs to 1,272lbs. IMO the present 900lb loaded tongue weight is on the lite side for your loaded 29BHDS and should be increased for optimum TV handling.
Not all of the weight removed from the TV's steering axle has been returned via the WDH adjustment (160lbs delta). "If" your TV's owners manual (in Towing Section) states that 100% of the weight should be returned when using a WDH, I would re-adjust the WDH (IMO plus/minus 50lbs would be ideal). In some cases TV manufactures on some model vehicles allow up to 50% (approx.) of the weight be returned (they refer to front end rise measurements), if this is the case then IMO 160lbs would be acceptable (3,600 - 3,200 = 400lbs @ 50% = 200lbs).
TV rear drive axle is (4,240 - 4,050) = 190lbs over its GAWR...., may not be a deal breaker for some, but does exceeds specified TV limits.
One rule of thumb that I use is when "multiple" manufacture specified limits are exceed by even a nominal amount, the summation of them all may compromise optimum TV handling under less then ideal towing conditions.
Again, great CAT scale weight information for folks to reference when considering similar TV/TT combinations.
