I just went to through all this, and despite possiby being attacked for saying this I went with the following:
2011 Dodge 1500 Ram, w/3.92 with the 5.7 hemi. I am allowed 10,500 on a weight distrubuted trailer or 15,500 total truck/trailer.
I went with a GN, 12,000lb trailer (same trailer as 10k, just bigger brakes, tires and slipper springs) liscensed for 10k so there are no combination plates. Used the B&W bolt in kit, which is awesome. Takes about 2 hours to put in and very simple install and excellent instructions.
So far I am super happy with this rig, and it works for me.
I also have a bumper hitch tilt trailer and its nice too, but for one tractor on a long haul once or twice a month. Can't beat the new rig.
