My problem with sun-drying is that in the late summer when you have a
glut of tomatoes the weather tends to be quite humid here, which will
slow down drying and increase the chance of moulds growing.

I may have to use an oven anyway.

I wonder if the method of drying affects the flavour? Any thoughts?

I use a dehydrator to dry my tomatoes. They taste better than the fancy
imported sun-dried tomatoes I've bought, IMO. (Maybe it's because I start
with better tomatoes, and mine would be even better if only I could sun dry
them.)
