There is no difference in loading a trailer and pickup as any other transport. The following rules apply.
Load the heaviest items from the bottom up and the center out. The goal is to have all axles bearing approximately similar weights. Tongue weight must be 10-15% of trailer weight. So, add this to the rear axle weight unless a weight distribution hitch is used them add a percentage based upon the hitch manufacturers claims to distribution to the front axle. If you don't know, assume 10%.
Then, add weight to the trailer and the truck to get the balance approximately the same on each axle. If you have a two axle trailer and a 5000 payload, the rear axle of the truck will have 1600 pounds of the truck's own weight and about 600 pounds of tongue weight. So, if you put everything on the trailer it will be about equal on all three axles. Maybe the bed could use 300 pounds or so. If you have 10,000 pounds, you will need the tongue weight, now 750 pounds plus the 1600 of the truck, and then add 1000 pounds for a total of around 3300 on each axle.
Math is approximate, but you get the idea.
