looks good....
That really blings up the interior!..the only downfall is ...
..aluminum VS steel= battery!..
I hope your floor was painted well before you bolted it down..keep an eye on the bolts,eventually the aluminum will turn white and salty looking around the bolts,and will erode a big hole around the bolt due to electrolisis..its best to put tarpaper or some sort of plastic between the steel and aluminum,(or paint the underside, or bedline it)..and use galvanized bolts,and replace them when any corrosion is evident..
I have a 12' "reefer" truck body in my yard for storage..its diamond plate aluminum floor has a 2" hole where nearly every bolt held it to the channel iron floor joists!..

...its real "slick" if it gets wet too,despite its "tread"..
I do like the looks of diamond plate though..I have "bed rail protectors" of aluminum on my 79 C10,and I chopped an old diamond plate running board up to fit the steps on my 82 stepside--they go well with the aluminum diamond plate tool box..its a pain keeping the aluminum bright and clean here in "salt east" MA though....
