Just make sure your rough cut boards are reasonably dry, as they dry out they shrink leaving huge gaps between each pair of boards. I re-decked my crane truck with rough cut fir from a tree that I had cut and transported to a local guy that had a band mill.Quote:

Sorry for the delay. Still have yet to assemble the trailer. Life won't wait, and the weather sucks here in the Pacific Northwet when I gotta do everything outside. Hope to get it together before the end of the year.
Lots of mills here, timber is a major industry. Pretty much all the lumber is high temp kiln dried, so I have to worry about swelling rather than shrinkage. It rains nine months out of the year here. Snows sometimes. Did a little last week but not enough to have fun in the Jeep or Subaru.
The best decking material that i can think of for a trailer would be pressure treated 2x6 or 2x8. It doesn't need any care and will likely last 20 years or more out there in the elements. What you wanna do is look at the endgrain and put the crown facing up. That way the boards don't cup and hold water. Use a sixteen penny nail as a spacer between your decking boards as you are laying them. That little bit of space between the boards allows them to shrink or swell without causing any problems.
If you had a small 4x8 trailer ... a 4x8 sheet of pressure treated plywood would be just right. You could probably get by with 1/2" but 5/8" or 3/4" thick would be better.
Another thing that's gaining popularity these days is what's called composite decking & boarding. It's made out of recycled plastic and sawdust. That's being used on a lot of high end jobs now because it's maintenance free and lasts indefinitely. It doesn't swell or shrink so that's a plus. It is kind of expensive to buy though.
Kinda concerned with pressure treated wood because it's corrosive, code requires galvanized or stainless fasteners and hardware in construction. Plus that $#!t is heavy, had to carry 16 foot 2x6, 2x8 through soft muddy backfill, really sucks, or sinks me down. Built alot of decks with Trex, the composite decking you described. Heavy material too, gets hot in summer and slick as snot on a doorknob in winter.
I was primarily thinking about low maintenance and durability. They most often use Southern Yellow Pine and then drop a whole lift lift of that stuff into a vat of water and preservative. Next they seal the vat and pressurize it to drive that stuff right into the core of the wood. Point being ... it's about twice as heavy as K.D. because it's so heavily laden with water. It takes about six months for it to dry out after it's been installed for it to be somewhere near normal weight. SYP is rugged enough without getting the density you would get with oak planking .... or ... heaven forbid ... ironwood.Quote:

As for trex ... it's just an idea. Personally, i would go with PT but it's an option.
This is getting way over thought. It's a harbor freight trailer. It won't last that long. Not trying to bring you down, but it won't. Don't do the composite. Slippery when wet. Same with treated. You don't notice it on flat surfaces. Just plain old rough cut true dimension wood. I wouldn't worry about shrinkage on it, and if you're worried about stuff falling through an inch gap in a trailer, you're not loading it right.
For 20 bucks you can get enough rough cut. You could go 2 inch on the floor, but for the size of that trailer it's over kill. You'll never haul anything heavy enough to need that thick of wood in a thin wall trailer.
You're going to find you're going to sell trailer anyways. Everybody starts small and regrets it.
Just make it so it's useful and legal. Next time you're at the yard, look at the trailers that are coming in. You see someone with an aluminum trailer, and shiny truck. And you know you shake your head, because it's just not cost effective.
My best gooseneck trailer floor for scrap is 3/4 pressed metal (some call catwalk) and the front 8 ft. pressure treated lumber. It is an old stock trailer that I cut down and created a (tub) scrap trailer. The front wood portion is for prepared metal or anything that will fall out of the pressed metal portion. The reason for two different floors was to allow water, snow, and dirt to drain and limit shoveling. For a small trailer that is being discussed I would consider using buckets and tubs for small items and use pressed metal.
I built a 20 ft. trailer for my son to haul his side by side and other toys or vehicles if need be with the axles from a stock trailer. The entire floor is pressed metal because it is strong, light weight, and he can elevate the tongue in storage to eliminate snow and ice build up. The only thing he dislikes is the dust kicked up from the gravel roads.
Finally got some time to do things. Set up the wire stripping machines and going to work on all the romex first. Started assembling the trailer yesterday, should have it mostly finished today. Will have to go to the DOL and get a State Patrol inspection form. Probably do that when I renew tabs on my Subaru, $96.25 for something that's 18 years old!!!! It's a four banger getting around 25mpg so will use it for scouting CurbCo or small pickups.
Haven't been active at Curbco lately but I passively find a thing or two, like a microwave manufactured in 1991. Can't wait to see how much copper this baby has, she's heavy. Got another half dozen other microwaves to tear down too, and clean up my mower junkyard. 1/2" cordless rattlegun will make short work of all the mower engines. Hoping my first load of the year breaks my old record in pay.
