It really depends on the trailer construction. I have a 25 ft ultralight without a slide. It shares the same frame section and suspension as a 32 ft version that weighs almost 2000 pounds more. Manufacturers save money by using similar components. That said, I have found my trailer to be very stiff when using the stabjacks. I really don't hear the creaking others have described. I really don't load the jacks that much, just enough to center the bubble when it is on the center mark, but off to one side and bit. I think there are so many variations of trailers and types of construction, each owner should evaluate what they have (do some research) and decide what they can do with what they have.
