The message
from "H Ryder" contains these words:

What on earth do you use a bucket to pee into for? ...Only
if it is so cold that you dare not pee outside a tent do you need a
bucket.

I take it that you are one of those "fair weather campers"

Nah, Nick is recalling tents in the good old days before the
sewn-in-ground-sheet was invented.
