HELP need pic. What seals the waste plumbing through the rear crossmember?
Here's a pic so you know where I'm starting... I'm trying to re-engineer the rear end, water gushing, funnel system on the original design while I've got the shell off and going to get the welding/ fab work done.
Sooooo... I've got some ideas on how to direct water away from the floor, BUT
What is supposed to fill the holes where the waste tank plumbing comes through the rear crossmember? Some one told me a piece of rubber like a thick bicycle tube or something, but I am having trouble understanding...
Anyone have any pics you can share? Or any of your own improved engineering designs?
