Who doesn't like digesting more scale numbers!? Setting up my new 2021 F-150 HDPP (7850 GVWR, 2536 lbs yellow sticker). TT is a Coleman 262BH, 7600 GVWR, 30' bumper to ball. Hitch is a Reese Dual Cam, 1200 lb bars

First pass, truck only (mostly ready to camp, missing about 200 lbs of people and another 200 lbs of stuff in the bed.
- TV Front axle = 3410 lbs
- TV Rear axle = 2772 lbs
- TV total = 6182

Second pass, TT hitched, no weight dist (bars in bed)
- TV Front axle = 2992
- TV Rear axle = 4290
- TT axles = 6358
- TV total = 7282

Third pass, TT hitched, WD bars attached.
- TV Front axle = 3212
- TV Rear axle = 3828
- TT axles = 6490
- TV total = 7040

Fourth pass, adjusted the hitch head a bit further back in attempt to transfer more weight to the FA:
- TV Front axle = 3388
- TV Rear axle = 3586
- TT axles = 6600
- TV total = 6974

Lastly, checked the TW with my Sherline scale it was around 1000 lbs.

I am happy to get the weight on the TV front axle back to almost what it was without the TT. I think that is success. I drove it to the scales in the "Third pass" config and home int he "Fourth pass" config and both felt good. Also happy that I have roughly 800 lbs to work with on the TV payload.

A few thoughts / questions:
- if I add up the TV/TT numbers for the three full passes, they are 13,640 13530 and 13574 each, that is probably within the errors of the scale I think (?).
- I am pretty sure my tongue weight is roughy 1000 lbs, seeing as I verified with the tongue scale, and the second pass with no bars added 1100 lbs to the TV total. However why does that drop when the bars are attached. The numbers say that weight is transferred back to the TT, is that expected? If I think about the angle of the TT being more level I can see that, vs when it's nosed down with no bars attached.
- I am slightly nosed down overall with the bars attached by 2" end to end on the TT. To the eye it looks level, but I might move up one set of holes on the shank if I get motivated before the next trip, or not.

By the way, the truck is awesome, so much power and so smooth compared to the old 2500HD Silverado gasser!

Cat Scales are your friend and helps keep one honest. I have used them from Texas to NM to Oregon on 3 trucks and a TT. Keep the results in my glove box.

CAT scale numbers will be the ones you need.
Fourth pass rear axle weight = 3586 lbs. First pass rear axle says 2772 lbs = 814 lbs for hitch and other gear in the bed and a % of weight in the back seat of the truck.

That 2772 lbs first pass is a very heavy number for even the F150HDPP rear axle. Hell my 2500 Dodge/Cummins 2wd quad cab NV5600 short bed rear axle is just 108 lbs heavier. You must carry lots of "stuff" in the bed and back of the trucks cab.

Your Sherline is off by 10%.
First pass just truck 6182# on the CAT.
2nd pass with trailer no WDH truck was 7282#.
IOW, your tongue weight was 1100#.

Great job on weighing your rig, step by step, PROPERLY!

I think it's pretty normal, RA was 2222 lbs straight from the dealer with me (200 lbs) and a full tank of gas. I have since added running boards, line-X, an overhead rack for kayaks. At the time the bed had two camp chairs, a folding table, three bikes and some other random odds and ends.

To get a accurate TW with a scale under the coupler, the tongue needs to be the same height as when towing. When you unhook the spring bars, the tongue goes down which transfers weight to it.
