This is a very helpful thread thank you!
I also just bought a Sherline tongue scale and my X213 is 650 on the nose.
* Full Propane tanks, spare, but no WDH hitch or bars in storage on the trailer
* Four lawn chairs, a folding table and some other light misc items in the front bunk area
* Massive 3-burner camping stove, two heavy griddles, about 100lbs of supplies all packed under the table
* Black, Grey and Fresh tanks are all empty
The trailer is 4,400lbs empty and I am pretty sure I am close to 5,000lbs with it packed, so 650 for a tongue weight is 13%, or pretty much perfect.
One more thing - be sure to weigh your hitch at PRECISELY the same height as when it will be hitched on your vehicle. I noticed the weight could change 50-100lbs just by moving the hitch up or down an inch or two!
