Replacing Flatbed Floor ?? is it worth it

I have a 1995 48' spread fontaine flatbed, i got this from a broker that tried to screw me over for a load and ended getting this. Its missing about a 4'x3' section of the floor but the rest is really cracked and would probably need to be replaced. I'm not too thrilled on dumping money into it since i figure its like putting lipstick on a hog but, what kind of money should i be expecting to get for it ? I also have a 98 t2000 i put in a low mileage Detroit last winter and its just been sitting on the yard so if i dont find a buyer i think im gonna end up trading it in to start a new venture with a flat/drop/curtain or reefer because hauling dry van is not leaving much $$ thanks for all your help
