Believe me I had those concerns. When I was designing this setup I knew I wanted to set the ball under the rear of the front trailer closer to the axles to reduce the "whip" that tow vehicle overhang gives a trailer. I also know that the shorter the tongue is in a trailer the more the severity of that whip is magnified. That is one reason I chose to lengthen the second trailer tongue the extent I did. I was not sure just how far under the front trailer I could put it before I would encounter the problem you mention so I did a lot of measuring and calculating. There is 22 inches of clearance under the rear bumper of the Bigfoot
on a level road. I set the height of the 10' 3x3 tongue at 8 inches above the road and 11 inches below the bumper of the trailer. I checked these measurements, clearances and angles with the 10' tongue before I bolted it to the second trailer. There is an additional 4 1/2' of length from the front of the second trailer body to the axle
making the total pivot length 14 1/2' You could raise the trailer wheels 53" off the (level) ground before the tongue would make contact with the under side of the bumper. I carefully approached and positioned the trailers in some uneven driveways near my home and checked the clearances before I started out. During my trip I avoided a few excessively steep or uneven driveways. I crossed the less steep and uneven ones at a diagonal angle. The tongue never made contact with the "tow trailer" or dragged the ground anytime during the entire 3550 mile trip. I do have to watch where I am going and I would not want the tongue any farther under the front trailer. Here is a picture of the trailer with the longer tongue hooked to my ATV at the Bonneville Salt Flats. I will take some better pictures and post them.
