Carpet replacement(s) - but with what??

For those that have done laminate floors in place of carpet, did you put any underlayment down for insulation and/or sound proofing? I settled on Pergo Max that comes with a padding on it. The instructions say that despite the padding that comes on them to use an underlayment moisture barrier. I'm thinking this would add more temperature and noise insulation as well.

I installed a composite laminate with attached backing and also used a rubber underlayment membrane. There is definitely a moisture break doing it that way but only about .26 R added insulation value. My trailer has an aluminum cladding underneath so I wasn't terribly worried about moisture intruding from below. The underlayment does absorb noise and adds some more cushion to the floor,
