That could possibly work. Just make sure of the dimensions. The one I built is 43" wide and 30" long and 10" deep. I used 1/4" steel and a little imagination on the latches for the tailgate. I attached it to the rack with four heavy duty u-bolts. Does take about 10 - 15 minutes to take on and off. Cost was approx. $50 including the u bolts.
