Trying to remove our thetford toilet C250 the four screws are rusty and proving difficult to remove also having to work in a small space any advice would be appreciated does the toilet bowl come out to give me room to work from above (Just a thought) thanks

Looking at the exploded diagram on this site suggests you'd have to get underneath the toilet assembly to release the bowl.

So that's probably a non-starter.
Probably perseverance with a fresh and un-rounded screwdriver that's a perfect fit may help. Also consider a screwdriver but in a socket set with a long reach drive.
Once you DO get the thing out, replace it using fresh, stainless steel screws.
