Ok I have a Rockwood Roo 23ikss max gvwr of 6684
TV 2018 Ram 1500 bighorn 5.7l , 3.92 gvwr 6900 payload 1680, towing capacity 10300, max gcvwr 15975
Hitch EQ 4point 1000/10000
So I hit the Cat scale 4 times, first just TV with family, full tank of gas
2nd TV + TT no WD
3rd TV + TT w/ WD,
After not being happy with 3rd ticket I went and readjusted the how the TT was loaded, removed a bunch of stuff we really don't use, and moved stuff like the Anderson levelers, x-chock and lynx levelers to the outside storage above the rear axle. Also the 2nd and 3rd ticket had no water in FW tank.
So filled the FW as we camp April-May with no hookups June-Sept have hookups. To adjust for the FW tank I removed 1 washer giving me the 4th ticket. Only concern now is TT axle weight rating which is 3000lbs each axle. But at the same time I regained 260lbs of payload on TV. I can move the Anderson levelers and such back to the front storage from storage above axle. Or not worry about it as I am still under TT axle rating and this is the last trip with water in FW tank.
As far as towing goes with the 3rd ticket I felt like I had too much WD, front fender height was also back to unloaded fender height. 4th ticket was a very smooth tow. Front fender height is still more than half way back.
