Thanks Ron.
You are correct, WDH was not attached when I used the Sherline.
My fresh water tank is located near the very back of trailer. Thirty five gallons would weight approximately 280 lbs. I think it's quite possible that could take 200 off the tongue. However, even with a full fresh tank, I should still have close to 1000 lbs tongue weight. That would be about 12% of trailer gross.
BTW
The WDH is one of those new Andersen WD hitches.
Numbers listed for wheel well heights are as maesured. You suppose the Timbren SES has something to do with that?
