NovaKool. Local company (Coquitlam) and available at Steveston Marine so no shipping costs. One or more of their units are usually on sale. There is one particular model that fits in the 74/75 westfalia fridge space so if mine ever packs it in or I want a unit with half the power consumption that is the one I will buy. I believe the Truckfridge will fit as well.
There might be other units available. I would check around with the local long haul truck parts shops - Cool-it, Western Star are a couple.
