Default Cypress Trailer Bunk Boards

I need to replace the 3"x8"x8' bunk boards on my trailer. I'm planning to use cypress rough sawn to dimension. Can I use it green and not worry about warping?

If this isn't an emergency repair, what I would do is to purchase the boards and let them age for a month or two. If they twist, return them to the store.

Do they have to be cypress? Lots of people are using pressure treated landscape timber with good results, and that would save you some bucks.

Isn't cypress used because it is heavier than pine, and will not be as likely to float the trailer?

Cypress is heavier than pine but also naturally resistant to rot and pests.

My new trailer has bunks that are made from box aluminum, about 2" x 8". Hollow on the ends. No worries about flotation or pests.

I had pressure treated bunks on the earlier trailer. Never had trouble with it floating, but that was a galvanized steel triple axle, which weighed 1830 pounds.

New trailer weighs 1050 lbs.

Because of its weight, rot resistance and strength, cypress seems to be the best material for bunks. It is far stronger that pressure treated wood, which means the attaching bolts and staples won''t pull out as easily. I'm not comfortable with the idea of aluminum box tubing because of its stiffness. Any area that has a lot of load is going to result in the carpet wearing through very quickly, whereas wood will compress a bit and slow the wear.
