CB500X camping trip. Right bike! Wrong camping gear?

Описание: "Is it just me, or is it cold in here???"
This video is my first camping trip on the CB500X and only my 2nd camping trip in many many years. It is in preparation for my big European trip Spring / Summer 2022.
The CB500X performed flawlessly as I expected (and by the end of the trip, the engine was fully run in).
The camping gear caused me concerns, we had a mini-storm in the UK and temperatures overnight fell, with high winds and rain, leaving me chilled until I added my biking jacket as an additional layer. Was it the dome tent with 4 mesh walls? My sleeping bag? Sleep wear? Sleeping mat? All of these? Adding a Tarp improved matters, but as I did not have confidence that the tent would withstand the battering overnight, it seemed I woke up with every strong gust.
Maybe I have the wrong expectations and I should have worn more layers to sleep in?
Being a novice camper (yep never too old to start) I'd welcome your thoughts.
