Please someone, correct me if I'm wrong, but 99.5% I'm right on this :
Nope, you can't create a wide load - so by putting them side by side, you do.
Can you cannot put them as 109 wide either. If there is a way to put the pieces on the deck without it being a ' oversize ' load, you are required by law to do so.
you need to put one piece 109'' long x 53'' wide and then the other piece after to give you a total of 218'' of deck.
No other way to do so.
Cheers!
