LOL noone wants to be an ass so I will. If you cant get off your butt and start doing something, whether it be get busy on the truck or working then dont bother doing anything. If your confident you can weld that frame up properly then get at it and quit typing about it. Maybe you dont have the skills to do it right, but you have an experienced welding instructor who can guide you and correct you when you F up. The c channel size you need is the same size as the frames you are butting together, measure it. Talk to your instructor about metal types and the proper type of metal for a vehicle frame, and depsite the wisdom of all those smarter than me on this site, if its a farm truck and not on the road often, what better place to test your new skills before you do build a road worthy vehicle. Everyone has to start somewhere. If you do good enough and realize you have the knack for welding then you can start making money doing small welding jobs just like the fellow above did with his computers. But again the point is quit sittin around and make a decision already. There is a fabrication section down below that I suggest your thoroughly read all the posts. Learn what you can.
Sorry but sometimes someone has to be the ass. On a positive note, hands on is the absolute best way to learn anything in my opinion. Build the truck take it in a field and ride the hell out of it, try to break t. Find your weak spots and improve what you did. Its called R&D.
