FWIW I made some comments in a prior thread on the bumper topic. The front end is almost overloaded from the factory, so a 400 lb bumper and 200 lb winch may be too much. Also, look at the front frame horns first. The front frame section gets its strength from shape (box section) not material thickness, which is only 1/8". Furthemore, only relatively short tabs stick out to hold the bumper. Not too stout. Most aftermarket bumpers are higher than the frame so if something hits them, they will have leverage to kink the frame. Ideally the bumper will extend down to the bottom of the frame horn in an attempt to make any impact straight-line. If you look closely near the firewall, you can see indentations in the corners of the frame like it was hit with a hatchet. These are designed as "crush" inducers, so overdoing it with the bumper may be counterproductive. The leverage from a strong brush guard to kink the frame would be tremendous. You have to decide if you want a less stout bumper system that will collapse (albeit less readily than the wimpy 0. 080" thick stocker) and hopefully protect the frame somewhat, or you want to keep the bumper, and put it on a new frame.
On a similar topic, if everyone isn't too bored, the rear frame section is a lot stronger from the standpoint of bumper mounting. It is 1/4" thick with a strong H crossmember to help keep it from getting out of square. I recently finished my rear bumper and used four bolts per side to mount it, with the forward position being the short slot that is between the two tailpipe bracket mounting holes in the frame.
Sorry if this sounds too pedantic. I am disappointed that Dodge does not offer us a truly HD frame option, and that it is hard to mount good bumpers, the stockers are junk, and all aftermarket stuff I have seen is designed less well than I would like. When get to Texas for the meet at the lake, maybe I'll get to see some of the stuff made there, like Ranchhand, etc. and maybe it is better than what I have checked out so far.
