As you know, there's only one bit of a Stratos that is a problem in Saltwater - the back deck support is made of steel that's way too thinly galvanised and it'll rust.
I'm getting mine re-manufactured in stainless steel and I'm sure that there are others who will want the same.
Can you please email or PM me if you want to be part of a group purchase of these - I'm sure that I can get the price down as the numbers go up. No idea of pricing ATM, but they won't be super-cheap due to the fact that they'll be made out of stainless steel.
It looks like a reasonably easy job to replace the existing one - you just need to replace a swatch of carpet that's above the rear seat spigot mount, otherwise, it's a screwdriver and shifting spanner job.
