Draining V cross members

I noticed that my V cross members don't have a drain hole, they fill with salt water.
Would I cause any structural weakening if I drilled a small hole at the bottom of each?

Won't hurt. How is water getting in in the first place?

I don't think that is what he meant. How is the water getting into the tubes? Are they open on top...or past a weld...etc?

V,,,,Duhhhhhhhhh, you said that. I don't think a hole in the center will hurt anything. I would keep it small though, maybe 1/8 or 3/16.

The ends are open, they are at the bottom of the trailer so the water stays in the V part.

If the ends are open won't the water just run out going down the road as the trailer tilts from side to side?

My two cents worth. When rinsing at home water will stay in the cross member. No driving after it is parked. Good question as I have wondered that myself. I actuall run water into the crossmember on purpose to get the salt out. If left in it will rot out the metal (aluminum).

I have been running the hose in the ends when I get home.
I went ahead and drilled an 1/8th inch hole in the center of each one, I bet at least a half gallon of water came out.
Thanks for the input guys.

Now that you mentioned it, I went and took a look at the crossmembers on my trailer. They have 3/8 drain holes in the bottom.
