Only the manufacturer can explain what is meant by their ratings. The Eaz-Lift website describes a 1000 pound hitch as being able to redistribute a 1000 pound tongue weight. This is, at best, a simplification based on the "average TV rear overhang" and " average hitch to trailer axle center distance". Certainly, the chain tension is doubled if two chains are under equal tension.To answer your previous point, from equation 8,
D= (T*H*L)/(B*(H+L)) hence
D/T=(H*L)/(B*(H+L)) This shows that a total chain tension can distribute a tongue load greater than that chain tension, if (B*(H+L) is greater than (H*L).
