you will save cash by building your own and luckily they are really simple to make.
ideas: look at tons of pics find a style you like and make yours from that. take a pic of the front of your truck and up load it in to paint. then draw out your ideas so you can see if they would work with the lines on your truck.
tubing size: 1 3/4 .120 wall welded wall tubing. there is really no need to to go make it out of dom.
skid plat: the best would be made out of 3/16 or 1/4 thick aluminum.
mounts: i made custom mounts you can see them all in my photobucket. or you can just weld it to your frame
just mig it.
best of luck. pm me if you need help.
