Spinifex mawson 8p vs second hand Coleman Gold 10p

Hi, I’m a single mum, 2 kids (3 and will be 9), have not been camping since I was a kid myself so my brain is hurting from trying to work out what my best options are for a tent and for setting up in general.

Hoping to camp at easter and chisels when it will be very hot and there’s usually a few storms.

On a budget!

Which of the two tents would you get to start out, in terms of longevity and water, particularly dealing with the heat?

I have looked at smaller tents but my life will be easier if at times my 3yo can be zipped into a play space so 2 rooms or enough space to play is required.

Size - bag needs to fit in a medium SUV.

Thank you.
