Body is 188lbs, rolling trailer frame is 203lbs and tongue box is 20 lbs for an estimated total of 411 lbs. Without bed, propane or shelving. The trailer frame is now under the trailer box and I have sorted out the problem with the rear door. I did make a fairly long tongue on this trailer so by putting the tongue box on with a large size car battery and an empty 20lb propane cylinder in the box, I was able to get inside without tipping the back of the trailer on to the ground. So I consider that a win, and the tongue weight shoud be more than adequate for a smooth ride.
