Anyone use a carboy harness?

[Brew Cat]

I am 73 and still fermenting. About eight months ago, I built a three tap keezer. The down side: keeping it full is a lot of work. I prefer glass carboys. I don't trust plastic. I do have a harness, but I built a four wheel cart large enough to hold two car boys. Much easier !

My keezer is an upright. Makes tt much easier to manage kegs and fermenters. I basically slide them off a rolling cart. I'm over 70 as well. When I was younger I used a chest type.
