Welcome to Myswag.
Not been here long myself but they seem to be friendly bunch
We're just making the leap from tent camping to camper trailers and have just put down a deposit on a Cub Supamatic.
The Supamatic is a little bigger than many hard floor campers, both width and length. It would potentially make quite a good base for a family.
The kids could sleep in their tent and leave you in relative peace inside, or if the weather is really bad then all 3 kids could sleep on the camper floor as it's big enough.
If you're looking at buying new then they are based in North Rocks and they are great guys are great to deal with.
There are also plenty available on the second hand market as well.
Good luck with the decision.
It only took us about 3 years to decide, though the arrival of our daughter part way through meant we had to had to start over.
