Update: I bought a a new TV, 2019 Ford F-150 5.0 3.55 gears 10 speed automatic supecrew 5.5' bed.
Moved the Hitchhaul to the new truck. It recognized the vehicle, asked is this your VIN, yes, and it loaded the library calibrations. I did recalibrate the load to be zeroed to my standard carry.
I finally took the time to connect the new TV to my TT to change its storage location (blocked the view and SWMBO's plants by the garage ;). I drove it over to the high school parking lot Saturday to measure changes unhitched, hitched, and with WDH. also to check weights with the Hitchhaul. After getting all my height measurements, I realized I failed to check tongue & WDH values. It was hot out so I went home to get the tongue weight and WDH values.
Results: tongue weight 460# for 12.5% using previous CAT scale TT weight.
The WDH charts were harder for me to understand. It appears if the little yellow mark is in the green zone in each of the three vertical scales, it's good. I had to watch a Utube video on it to understand.
Why did I use my previous CAT scale reading for tongue weight percentage? Well, the GCW read 8200# which after subtracting the GVW of 5600# was only a 2600# difference! TT dry weight is 3166#. I didn't note this till I went inside to review values and cool down. I'm not hooking the TT back up now for a reweigh trip. IF I misremembered the GCW by the time I wrote it down, say 9200 vice 8200, that would make sense.
I thought maybe there might have been a difference because my original TV weight was taken in standard drive mode and the GCW was taken in tow/haul mode. I did take a quick drive to check that but I got the same TV weight in both driving modes.
