The total rolling load when I was making the last move for my shop was around 29000lbs. It was strategically planned as the heaviest load, but ended up heavier than I expected. I had the skid steer at the new shop for unloading stuff under about 1500lbs, so I had already unloaded most everything. But there were a few things that could only be loaded and unloaded with the forklift. I already had the lathe/mill/drill press/tying up my other trailer.
The final load was a 10hp air compressor (1300#), a pallet of miscellaneous steel (~2500#), 5ftx5ft by 2" thick steel welding table (2500#), 8x22 hydraulic tilt trailer (4500#), 03 Duramax (7300#), and Cat T50c forklift (10700#). Totals up to 28,800 pounds. I had to go about 4 miles with 2 turns and 1 red light, and I had my dad in his truck in front of me so that no one would pull out in front of me or do anything unpredictable.
