I heartily recommend a summit top camp for SOTA, but obviously ensure your equipment is up to the weather forecast.
Even with just 2m VHF, i find all sorts of interesting contacts through the night. On HF in summer it is even more interesting.
Operating from a sleeping bag, while the weather outside is bad is great too.
I have an aim to camp atop all 4 point and above summits in the lake district, this is how I am doing (I suspect I will never manage them all, especially since some are rather rocky and small (eg Pike o Blisco) but it is a good thing to aim at)

A night atop Grasmoor (G/LD-009), and Grisedale Pike (G/LD-015)
