Hi
@Ghillie
Five kegs will be a tight fit, but they will fit!
Any problems removing the front kegs could be resolved by removing one of the rear kegs, "shuffling" the others around so that the front kegs move to the rear. A faff, I know, but do-able.
A less pallatable solution would be to space the taps out around three sides of the keezer so that they do no rextrict access. This will spoil the aesthetics but it would be a possible solution.
With 5 kegs, there is bound to be a couple of beers that are less popular than the others - put them to the front.
Next idea - direct from Heath Robinson! Split the front part of the collar, hinge the top half and mount your taps on that part. When a keg needs to come out, swing the tap section forward, thus getting them out of the way.
I'm ready for my medicine, nurse!
