Hi Sean, I am actually Carolyn Katie was Busters date for a Yorkie Talk event. I haven't ridden for a while but my brothers do. The are members who ride on YT. With the indoor units you have to deal with the cleaning of the trays and the grass as the yellow flows down and pools leaving residue and the poop well you will have to wash the grass as poop leaves residue too. The crate is a good idea for puppies but Buster is good so he has run of the place while I am at work. For me the pads work because i have less cleaning up to do as I have a separate closed lid trash bin reserved for the pads in my bathroom I just pick up the poop and flush it. I use a steam cleaner for the floors as the steam kills bacteria and I don't have to use harsh cleaning products. The Global paw print is a bit large with the amount of pads going to landfill so you can use the washable ones if you want. You can buy them online cheaper. I always rinse them in the tub before I throw them in the washer.
