Hi Morgan and welcome. I'm another from North Cooma, also known as the Tuggers area. Like Kiwi Pete I have two fridges, 60ltr in the track and 40 in the CT. I also have a 32 but that's for game meat.
By chance I happen to know someone who knows their way around electricery, I did it on aircraft for 20+ yrs so if you need a hand just PM me.
With so many MySwagers in and around the ACT region we should organise a weekend down Blue Water Holes, 3 Mile Dam or Bullocks Hill Fire Trail (all in the Kozi NP).
