It’s very easy when you begin camping to over spec what you need. Simpler is better, and especially if you’re just starting off doing weekends, quicker (to pitch) is better, which usually means tunnels rather than domes,and smaller rather than bigger. On the other hand if you’re going to be doing weeks rather than weekends and you’ve got the storage and transportation sorted go big and comfortable.
Never seen the need for leccy hook ups or fridges, good cool boxes like Coleman Extreme or Igloo Maxcold will keep cool for ages, just feed them a bag of ice every couple of days and you’ll be good.
One of the luxuries we allow ourselves is comfortable chairs, which are usually bigger (to pack) than the typical folding camp chairs, but well worth it ime.
Tentipi, yum!
