How far you driving with it ? Locally I would roll with it, looks good, but a chain wrapped between the wheels on each side (one axle) would look even better, just on the middle trailer(center of the 3).
2 straps for the first 10 feet and 1 strap for every 10 feet afters. So 53 would be at minimum 6 all together. That's why I suggested a chain between the wheels on each side on 1 axle on the middle trailer.
