How thick of metal for frame connectors

BillGrissom said
I noticed that nobody puts holes in their frame connectors. The factory frame rails have holes in the bottom and sides. Is that to drain out water, or to allow coating the insides? I always worry about rust, so you might consider painting the insides of your frame connectors, using zinc primer at the ends for "weld-thru" protection. When replacing my floors, I washed and blew the front frame rails out and spray painted inside as best I could, and pulled a primer soaked rag thru (Rust Destroyer).

Will do :blob: Thank you Bill, I bet condensation can and will build up in one fast.... On my list todo,, denatures alcohol wiped down on the inside using a rag on an old fishing pole :D 2 small weep holes in the rear along with painting the inside with a primer tape one end up and poor a pint of primer inside rolling it around, then poor the left over into the other connector :glasses7:

Hmmmm;Yep water needs some way out!

for a test I will plug the 2 1/2 inch holes and see what one season does, park it up hill and pull the plugs and see how much water/condensation was in them :glasses7:

I used 1 1/2 X3 .125 wall and it fit over the rear frame rail real nice and tight

Yes, This is way I want it to be 3'' wide, I could live with 1 1/2'' tall :glasses7:
