I was tired of the undersized casters on my egg nest. Did an upgrade today on my XL Egg along with a good cleaning. These casters make a big difference.
The new castors are from a restaurant supply store. The brand is Krowne. They are rated for 220lbs per castor. I will let you all know how they hold up. They should make it easier getting the Egg in and out of the trailer.
I've never moved a thing in my life that a good set of casters didn't make better. I've scavenged them off many a trashed shopping cart. At the cost of a XL large egg, I think it is cheap insurance.
