Corrugated poly sheeting instead of AL

[GuitarmanFL]

Hey Guys:

My plan is to replace my belly pan with corrugted poly sheeting. It's light, easy to work with, relatively cheap, and impervious to water, and lot easier to install than the AL that I removed - and is in bad shape.

I'm keeping the banana wraps, for sure and banged out the dents so I think they will clean up well.

Problems, thoughts, high-fives??

Thanks,

Brek

Many SOB's use this and my thoughts are that this would be fine for an Airstream as well.

We have black poly sheeting on our 5er.

Hi Brek

It does not stand up to heavy gravel like you run into in Alaska but otherwise it has been fine on box trailers. You need about 1.5" flat washers to hold it up.

Thanks Guys - Anyone know the best supplier?

I would run with 1/16 lexan sheet or 1/8 black uhmw sheet. It costs a little more but is way more durable. The lexan would be the lightest and closest to aluminum thickness.

Hey Guitarman, how did this work out for you? I saw these sheets at Home D the other day. 4x8 sheets that they advertised for sign boards. I thought to myself, that might actually not be a bad idea! Plus, you eliminate the aluminum to steel corrosion aspect that leads to rivets popping loose down the road.

Hey SOA:

Good Question.. I haven't gotten there yet. I'm still waiting for my new rolling chassis, and have been biding my time polishing

I did determine the poly sheeting is what other RV makers are using that have a belly pan. So I figure it should hold up fairly well.

Curious: How much were they selling the 4x8 sheets for?

Thx,

Brek

I want to say they were only $15 a sheet, but they were only 1/4" thick. I think what most box trailers uses is a bit thicker

I'd love an update on how the corrugated poly worked for you. I've got a belly skin replacement ahead of me too.
