No issue, just requires more fasteners. 2x4s will be less prone to cupping and cracking opposed to something larger
i would pre drill holes before screwing down my self with todays lumber quality or they could split before your down . and i would leave a hair bit of gap . not snug to each other .
What kind of wood?Yah but fastners are pretty cheap!
Yep that's the plan. Especially since there will be a joint in the middle of everything
What kind of wood?
How long would they last.
I would spend some money to make sure that the time I spend building the deck will be worth it.

That actually is really good but also not good looking.heard of guys doing a used motor oil stain job for trailer decking .![]()

I know a guy did that to treat the wood for his house build.
As for trailer decks I would use some thing harder than pine or at least something that is no as vulnerable to pests like redwood
That is so true.Seal the bottom side before mounting.

Use a penetrating oil finish such as Super Deck or Penofin. None of that home depot garbage that sits on top then flakes off. With an oil finish when you want another coat, just pressure wash it real quick and throw some material on, no need to sand off the old stuff.
Should do fine, BUT, unless you are into lots of repetitive work, Do Not predrill the holes in the wood.
These are a little more expensive than regular sell drilling screws, but more than worth the money for the time saved.
I have used them, and they work very well. Not sure what brand I used, my local fastener store just handed me a bag full. These seem to be a good brand.

You have to be sure to buy the right length for what you are screwing together, but these make it a one shot deal.
The drill bit on the end drills the hole into the wood. The small wings behind the bit act as a spade type wood bit and drill the wood hole larger than the screw threads.
When the drill bit hits the steel, it drills a correct size hole in it. The wings snap off when they hit the steel, then the self threading part threads its self into the steel, drawing the wood up tight.
The wood is drilled with a clearance hole, the steel is drilled, tapped, and the wood is drawn up tight with one operation. Plus, if there is too much of the screw sticking out the bottom of the steel, its hard enough to snap off with a quick rap with a hammer.
They are available in lots of places, shop around to get a good price.
