Load Range E tires (I've seen GM 3500 series trucks with D's)
Limited slip differential
Second alternator. (sometimes an option)
The differential is a G80 locker. While not quite as good as some lockers on the market, it has always done well in my Chevy 4X4s.
If I were pulling a 5er at some of the weights I've seen advertised, I'd be opting for the duallie 3500 rather than a SRW. I'm not a duallie fan and would not consider pulling a 25-30' Airstream with one but there comes a time that the extra suspension and dual wheels are necessary.
