5.3 camshaft help!!

Hey everyone, I just picked up a 5.3 for my 93 yukon gt. I really wanted the 6.0 but it wasnt in the cards. So before i even put it in I want to put a cam in it. I will be using the truck as a daily driver and frequently pulling a trailer with two 4 wheelers and a dirt bike. Can anyone recommend a good cam suited for the job that might put me around the 6.0 power? Any and all ideas are welcome since i dont know what all the specs of a cam mean as far as relating the numbers to performance.
