Cam Specs.....where will the power be?

I keep coming back to this:
This is going in a 2nd gen ram 4x4 ext cab about 6000lbs
Stock converter 1800-2000rpm
3.92 gears
33"" tires
Intent is a well mannered streetable truck I can tow with and have good usable power without having to reach far into the rpm range. Ideally shooting for power for typical driving scenarios. Not going to see a track. Will retain factory multiport injection and will be dynotuned.

First off, what year exactly and I'm presuming Kegger intake?
And is that 6000 pounds combined weight towing? If it isn't, I take it's a 2500 or 3500? If you're using the kegger, have you modified it internally by cutting the runners and porting it? Gearing, tire size, and converter are favorable for a modified kegger. Also, what rocker ratio are you running?
