I've got a Chevrolet Silverado 1500 LS 4x4, and I'd like to install a plow. I want to avoid damaging the truck, as it's also my primary means of transportation. 

Do I have to do anything to stiffen up the frame, or can I simply install the plow as is? 

Is there anything else I have to worry about here (transmission wear, tire/suspension damage, etc.)?
