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.

Karl, back when you and I were both kids (50 years ago), automatic
transmission fluid (used) was the way to keep board fences from drying out.
Most popular was Chevron which was red in color. I pumped gas from age 16
to 21 and we would give it away to anyone that asked.
