Got the floors fitted and secured over the last two days, ended up using Phenolic resin coated ply, (as used in trailers and truck beds).
May have gone a little overboard with 18mm thickness but very happy with the results, it has a smooth waterproof underside and non slip waffle surface on top.
Where it joins the bulkhead I have cut an angled slot and pushed it underneath the raised outer edge just to give it a nice finish before fibre glassing in.
A bull nosed edge just keeps it looking neat along the edges but these will not be seen.
It still needs a little trim down the outside rear where the body tucks in and the fresh edges sealed but overall has gone down ok and feels very sturdy
