The crosswind landing technique is probably the same on a 747 or similar wide body as a B737
Nowhere near.
The 747 has its own special problems due to the configuration, ie wingsweep and pod ground clearance. On a 737, get to just above runway, chop power, both hands on wheel, wrestle it to the ground, don't worry about bank too much. On a 747, gradually reduce thrust in flare until levers reach idle stops at touchdown, simultaneously remove drift with rudder and maintain absolute wings level with wheel. More than 6 degrees of bank at this satge and you'll scrape a pod. The outer portion of the wings with engines 1 & 4 flexes downwards at touchdown as the lift comes off the wing, reducing the ground clearance.
If you try and land a 747 like a 737 you'll scrape metal.
