Dicor vs ProFlexRV for Underbelly Repairs
I'm getting ready to seal up my newly built Coroplast underbelly for the fresh water tank and was planning on using black ProFlexRV sealant until I noticed it specifically stated not to use it on EPDM...

When I needed Coroplast for our "former" trailer I found that prices varied wildly. It pays to call around. I ended up getting it for $15 per 4 x 8 sheet. I added some 2 x 3's between the I-beams in order to give me something to attach the Coroplast. Stainless steel screws and fender washers worked great. Overlap joints so they won't catch air as you go down the road. Small gaps can be filled with foam sealant. While it was opened up I glued some foam board to the decking for added insulation.
