Something simple I learned from Dennis Olthoff was to merely feel the tire temps when towing. The rear axle tires will run ever so slightly warmer than the front axle. And if the fronts are warmer, they are carrying more load and I would need to raise my hitch. The rears run slight warmer because the air flow to them is blocked by the front axle tires. Measuring the height of my frame to set the loaded distribution matched his advice perfectly. My Serpent Express is 14 feet. That is about as short as you can go. More is better.
