Tow and Load- How much can I lower?

[kombreeze]

I have 275-60-15 all around my 68 stepside. I'm building a resto rat rod combo and came to the conclusion I'm not going all out because it defeats the purpose. I want a truck and plan on using it as a truck. Lately I've been hauling bikes, rearends, lumber, cement bags, cruising, lake bbq adventures, tail gaiting, etc....the stance is ugly so I want to level it off but wanted to know what drop combos are suggested. I want to use it as a truck but look cool doing it. The best was hauling a couple of bikes last month just went with the theme of the truck....
