Sagging under belly

[Timeout]

I just Looked at my landmark key largo and see the under belly sagging. I pulled one side part way down and water was running out.
We just returned from a trip and did drive in a sever down pour.
Water is clear.
so I think it's road water from the tires and such as I found many openings around the axle areas.
My question is what do I do to get it all out so I can dry it up and try to seal things up so maybe it will not happen again? I really not wanting to drop the hole thing down and replace the insulation.

Thanks,
john

I drilled a 3/8" drain hole in the lowest point. I have read on here where some have drilled the hole and drained it then plugged the hole back up. I would leave the hole.
1) that way it will drain out the rain water
2) you will know if you have a leak sooner.

Fill the gaps with expanding foam. Some have carefully drilled small holes in the sags to let it drain on its own. Filling the gaps and covering frame openings will also reduce the entry points for field mice.

I seriously doubt there is anyway to have a water tight seal on the coroplast under belly material. There are so many areas where the water can and will get in. Can you imagine the force of that water spray off your tires @60 MPH? I did drill holes in the lowest areas of the coroplast, to get the any water to drip out. Since I am just an anytime camper, not a full timer. I even go the extra distance. I dont tow in the rain, if there is anyway to avoid it.

I agree it would be very hard to stop all leaks. I was thinking to try as you said to not drive in the rain as much as I can. So I guess after this tropical storm moves out and I can get back under I will drill a hole or two and let it drain.

Thanks everyone for your input on this.

Use caution when drilling as there are tanks located close to the Coroplast.

I think I will pull down one side enough to see where things are so not to drill in anything.

Thanks!

Get a piece of rubber hose that fits snug on the bit, put it on the drill bit so only a 1/4" of the bit is sticking out the end. Drill a hole at any low spot in the coroplast. Did this years ago and never a problem again.

Thanks just finished drilling the holes.
Will keep a eye out for water dripping. Got most yesterday with pulling down one side draining most of it out.
Thanks for the help. I really appreciate it very much.

Should not leave it open, because a valve leak will spill hazardous wast onto the ground.

I have used Gorilla tape and aluminum flashing for large gaps.

Drilled mine out by hand. Coroplast was easy to get through turning the drill bit by hand.

Well you already drill out the holes. One at the lowest point is all that is required. You are lucky it is rain water. You can have water from a leaking valve and you don't want that spilling on the ground. Don't ask why I know! Twice! The material, coroplast, is soft enough that you can hold a drill bit in your hand, turn it, and get your hole made quickly. Have a bucket under the hole and when 2/3's full plug the hole with the back side of the drill bit. Now seal the holes up so if a valve leak happens, the gray water or (may it never happen) black water will not go on the ground. Clean the coroplast with 409 or even Windex. Degrease the area around the hole(s) using 90 to 100% isopropyl alcohol or acetone. Cover the hole(s) up with Gorilla tape. Believe me it won't leak. At least mine didn't and there was a lot of gray water putting pressure on the Gorilla tape.
