Alignment specs

I'm curious if anyone knows or has alignment specs for our trucks? What have some of you guys done for a alignment especially since some of us are bagged. Nobody around here has the stones to try or bother touch a dropped vehicle weather its a static, coilover, bag or juice. So I'm trying to find some info on doing this myself.

Also what would cause it to be hard to steer to the left only?

your alignment shop will be able to give you stock specs.
as for what might cause it to be hard to steer to the left? what have you done to your truck already? i'm assuming your bagged... is it hard all the time or just sometimes? (certain heights...?) have a buddy turn your steering wheel and you look under the truck if you can and check out all possible linkages, strut rod, control arms, pitman arm... everything. check your castle nuts and make sure they're tight and have cotter pins in them. tie rods too...
