Those self tapping screws that Husky includes might work fine on a TT frame but there was no way I would trust they weren't going to break off in our 3170. I've snapped bolts like these off before trying to use them on too thick of steel and it ain't fun.
I copied MotorcrossCampers method above although I do wish I could have bolted them on before the frame weld butt. There just isn't much room under there.
So far on the front jacks I haven't attached the jacks at all, I just slide them under and screw them up where they work, I don't see a place to mount them at all in the front area.
They're a major improvement though!
