Renault T night heater

I’ve had my Renault a year now, and I still love it as a truck…it is 2020 model.
Only 2 criticisms I have had with it are firstly the headlights, they are hopeless, like candles…where as the latest models are LED, mine is bulbs.
I was going through the New Forest the other week in the dark and nearly took out one of the wild ponies.:roll_eyes:

The night heater works, but any other truck I have had, when you first park up after about an hour the cab is usually red hot, where as the Renault does not get anywhere near.
Also if on a few hours through night, it is still a bit cool when I get out of bed.
Is it just a fault on mine, or are they all like that.
