I love tents, and own three now!
I have a Vango pop-up tent for when it’s just me, and a Vango Tigris which is good 6 birth tent for when it’s the three of us.
I also bought a secondhand Outwell, which is a 4 birth, but would probably suit a couple but was not bigger enough for me, my partner and 10yr old son. If your interested, I’m open to offers (had a tiny tear in one corner).
All are waterproof and Vango’s are easy to pitch, pack up again. Also remember the heavier your gear the more petrol consumption you will incur.
The Go Outdoors near us has pitched tents to look at – they might do this your way and might be worth a butchers 😉
Good luck on finding your fab tent!
