Does anyone know where I can get my hands on an OE Coleman water jug Part #4735-2131? Or perhaps someone has used another type of jug for under the sink? I tried the blue coleman 5 gal pictured below, but it's a smidge too big and doesn't fit through the door opening of my 97 Laredo . An idea of the cost would also be appreciated. A google search for the OE jug leads me to colemanpopupparts.com, but they are out of stock.
