I have a toyup deck, worked great, it was all steel including the ramp. never had a prob with cracking at all. deff get under the deck lights, I did not get clearance lights on the outside, never seen a need but would of looked cool. super clamps are the way to go by far. most people I know used turn buckles to hold it in the box, I thought that sucked crawling in and out all the time, I couldn't leave my deck in cause I needed the box, so I put boatbuckles on, by myself I could load it and tie it down in one minute with out crawling in, just reach threw and hook up the boatbuckle and ratchet it tight, way easy. my deck is 7 years old now and works and looks as good as day one. decks are deff the way to go if only hauling one or two
the only oops I had, when I got the deck I did not have a spray in bed liner, fit nice and slid in easy, then I got a spray bed liner and it wouldn't slide in worth a damn and the extra thickness of the liner made the deck fit tight between the wheel wells, prob not the case with most but for me it was pin in the rear
I think it was a marathon aluminum deck that a buddy had, the only down side was the foot of the deck was so big that it would fit between the wheel wells so you had to have two people to pick it up and over, on he toyup the feet are "runner" that are as long as the box
