plywood floor in 29 xlr hfs

[forrest46]

I had a water leak over the winter in the toy hauler part of my 2017 forest river xlr . What kind and thickness of plywood should i use. When i took a piece to lowes it was a tiny bit thicker then the lowes plywood and also the lowes plywood didnt have as many layers to it. Should i be looking for marine grade plywood ?

Thanks
Forrest

This may be a good question to reach out directly to XLR with.

Maybe metric versus inches? When I've been to our local plywood specialty shop which has a huge selection of plywood, they get it in in both measurement systems depending on where their bulk purchases of plywood come from, offshore, Canada or the US. In Canada for example, 5/8" plywood is sold as 15.5 mm but a hard conversion from 5/8" to metric is 15.9 mm.

It's very confusing in Canada which is supposed to be metric. The building code calls a 2x4 a 38x89 mm. But if you ask for a 38x89 at a lumber yard, they'd look at you like you're an idiot. Grocery stores sell items in both lbs and kilograms.
