not sure how far you have come along since posting in January… but I am in a similar situation as yourself. I am modding the 8 ft straight bar to a kegger bar by using a Kegerator.
If you have already completed this please tell me which kegerator used or at least the dimensions and how the unit is handling being enclosed in a tight space. My biggest worry is that it will overheat, or worse catch fire being on nonstop for (hopefully) years to come in basically a box of wood.
Any input would be great, and if you haven’t got that far with your bar yet, give me a couple weeks and I will help you out… and most importantly get back to building your bar!
