Have pics of 67 C-10 with a load, how can I level it?

[The Big Green]

I have pics of a 67 with a trailer and Jeep and it can only sit in the feild with this setup, stock setup...lol. I have the stock bumper and thats the first to go, I can buy a good drop hitch so no real probs there but the rest is a problem. I need it level and then a stock cam and a different intake, I have the victor jr. intake and a 3000 stall. What does everyone use to help level this thing? I'm guessing a drop hitch though, well mines weak. I like the way its lowered in the back...lol...I want it that low, only level with no load. I need help, I know this truck can do it, but it needs a little help.
