Thanks again for the advice. I had to lower the ball 4" and the trailer is now perfectly level. Like I said I have 400# at the tongue. Rigs has a 500# limit on tongue, and 5,000# tow weight. It weighs 4,820#, so no carrying anything in the car.
Retired and loving it.
Got a new 2014 Grayhawk 31DS
Hoping to get away from the IL winters
