Ghettoriffic floating deck - need material help

In reply to clownkiller :

I like the idea of filling the pallets with sand. I'd probably try to bolt the pallets together (because the screws might work loose in the plastic)

Some earlier pics

In hindsight... I should have done it as a traditional floating deck, but it is ghettoriffic.  I had about 28 people over last Saturday.   Smoked a 15lb Brisket, 8lb Venison roast, and later in the night 10lbs of wings (which then got dropped into the 6 gallon cajun fryer) and had a great time.  

A friend that was over earlier in the week on Sunday was shocked that I finished.

Thanks for talking me through it guys.  I'm sure I could have made many better decisions.  But for something I needed to get done in a hurry and on a budget... it worked out.

I think I want to swap the waterproof sunshade for some type of roof panels as the next thing... but that can wait a bit.
