The wood deck on my heavy duty 5th wheel trailer hasn't had anything
done to it.

"The Kid" tells me to put a good heavy coat of used motor oil on the
two inch planks and let it weather. Good idea? better suggestions? The
trailer cost $7K and I'd like the deck to last.

Ferget that! You'll have a slippery mess forever, lubricating oils
never dry. Scrape it down, use some deck oil on it. Hit both sides,
road spray is worse than rain. Visit HD, Lowe's, wally world,
whatever you have. Can be had in 5 gallon buckets for really big
jobs, the tinted stuff will last longer under the sun. Unfinished
wood really soaks it up, plan on a couple of coats at least. Reminds
me to redo mine before the snow flies, needs to be redone every few
years. Nothing is forever if it sits out in the weather. My trailer
is fairly small, I use a 6" brush. Usually takes an afternoon to do
the bed, both sides, and the sides. For larger stuff, I'd probably
use a roller or sprayer. Takes about 2 quarts to do the equivalent of
an 8'x8' area, both sides.
