It's warm in the van when I'm not on the move. I'm lunching at Birch Services on the M62 and the van thinks it's 36 degrees, and it may well be right.
Co Ops (where I work a lot) tend to have good air con, as do M&S food halls, so I'm OK when on site a lot of the time, and in the van as well.
I slept right through Tuesday night's thunder storm. Our living room faces east, so it's in sunlight in the morning and shaded in the afternoon, but the front room gets unbearable, so my son has a big fan in there and the curtains closed to stop him evaporating.
The pup is quite lethargic and we've not been taking him for walks in the full sun and he likes to lick ice cubes and begs for one when anyone goes near the fridge, regardless of how hot it is.
