Estimated weight of the deck assuming 2x6 decking and 2x6 supports every 2 ft and about 10 lbs of harware would be somewhere in the 650-750 lb range. Prep you site at home to put the deck. Get 5 to 7 buddies, and a case of beer. Ice the beer at your house and have the wife start making some burgers. Bring buddies to house, lift deck onto the trailer, strap down well, transport home. At home unload the trailer and position the deck where you want it, (you will not get this group back together again). Once in place shake hands, share beer and watch LSU kick Kentucky's ass.
If you have to move the deck very far to or from the trailer, get 4-6 pieces of 10' platic sewer pipe and roll it out of the yard liek the egyptians moved stones.
The jack idea is a good one but with a total weight of only 700 ish lbs. Two guys should be able to lift one side, tilting it up, while you back under it part way and then all three of you should be able to push it on the trailer.
Lift with your legs and dont forget to get gloves for all your helpers.
