Correlation between weight and "quality" build

My next trailer is likely to be a Northwoods Manufacturing Arctic Fox. They are a heavy trailer, but on the other hand the model I am considering has a cargo capacity of 3,000 pounds.

Look at the cargo capacity of the lite RVs and you will see that they are built meeting the absolute minimum requirements. Many have such a tiny cargo capacity that you are exceeding it by only carrying minimal gear, food, and water.
