in the end it would prolly come out more like a 5500. with a 110s in the rear anda super 60, or 80 up front. but obviously it wouldnt all come together overnight. 700lbs? how much does onea them blizzard plows weigh? the ones with all the fancy hydro stuff. ? i just equate the extra weight to sumthin like addin a plow or a big ranch hand bumper with a big winch. now the extra umpf that the motor will make would urge me to reinforce the frame. but why not since it'll be doin welding anyhow.
