yes, the fifth wheel rating is different. your 6.0 should handle atleast a 36ft camper 5er and maybe more but your going to run into power issues because you don't have the duramax. the 6.0 will handle heavy loads just on hills you won't be able to go as fast. just  be sure to have a trailer brake controller because stopping won't be very easy without one

yes, you should be able to haul quite a bit more. i'd say being you have the 6.0L and not the duramax you should be able to handle atleast a 36ft 5er camper but your not going to be a speed demon up the hills and besure to use a brake controller because stopping will be an issue without one

I've a 2004 chevy 4x4 crew cab 6.0 gas w/4 spd auto with tow haul....I think its a 3:73 also, $1750 to install 4:10's in front and rear(because of 4x4)...but were towing approx 10,000lbs of Cardinal 5th wheel, sluggish on grades a little but stops well at highway speeds and I suppose thats what counts (brake controller)I'd like to put a chip in engine to get a little boost, but main concern now is transmission temp, it approaches 205 degrees in heavy traffic and climbing hills,bridges and such so I'm going to place larger trans. cooler to help....not so much worried about power such as passing as I am bout temps n trans (30' Cardinal) acually  it sits level attached to truck 2500 LT Quadrasteer

As I understand, the diesels are really hi maintenence eng. and also the gas vs diesel cost...may gravitate towards one in future
