I got tanked today. I picked up a pair cheaper than buying just one. 30gal and 21gal, from Amazon and Class A Customs. I linked to them in the Parts Purchased page. I’m deciding on a location for the indoor tank. I’m thinking over the wheel well. I also found the old kitchen base cabinet from round 1 remodel and brought it back in to the bus to test fit a few things. I rough framed the shower pan and later ended up having to move everything over a couple inches to clear the frame.
Like this?
