New bunks and bunk wrap

[Lost But Happy]

1 1/2" sounds right. By the time you use a washer along with the thickness of the bracket, you should be OK on a standard 2x. Drill a pilot hole. I use them on the bunks for my 18' walk-thru. Never had an issue.

I'm not a design engineer, so here is where I get to either sound brilliant or make a fool of myself. It seems the forces would be more shearing (side-ways) than up and down. I can see how a short lag bolt might not hold, especially in wet wood, if there were constant force trying to pull it out. But that isn't happening -- unless someone had their tie-downs connected to the bunks instead of the trailer frame.

Excellent. Thank you kindly LDUBS.
