Hello to the two E's and WELCOME to the forum.
I noted your comment re getting back into tenting and the fact that you feel dome tents are too complex.
I have to disagree with this comment as I take my 76 year old mother camping and yes you guessed it....she uses a dome tent.
She can also almost erect it on her own, just needs someone to help hold the stays/bows up while she hooks the first lot of clips onto them. And no, she is not a seasoned camper, she came on her first camping trip just 3 years ago.
Dome tents these days are very easy to erect, lightweight and waterproof which I think is something you need to consider.
If you do deside to go with this option, two brands that I would consider are either DMH or Coleman...mum's is a DMH Omeo4.
Other than CPs you can also consider campgrounds as there are plenty about that have the amenities that you require and are usually cheaper as well.
Rather than airbeds on the ground I recommend that you each get a stretcher and self inflating mattress, again this is what my mum uses and with great success.
With a stretcher bed I suggest that you go for one that has feet rather then rounded pipe legs as they are less likely to tip over when you sit on the edge of the bed. This is also a good rule of thumb when purchasing camp chairs too.
I actually got mum one from Kmart that also included an air mattress but we tossed the airbed in favour of the self inflater. The beauty of this is the self inflater slips inside the fabic sleeve and becomes part of the bed itself.
Am pleased to see you still have your Dream Pot, I love mine and use it both at home and out camping.
Re fridge...if you want something small you might want to try the little fridge from Repco, they come in at $399 from memory. I have a friend who has one and she is very pleased with the performance.
Hope this helps and good luck.
The worst day camping still beats the best day working
