Rv gray water tanks

So how hard are these tanks to remove? and where do you find replacements? My trailer has a 30 gallon fresh tank and both seperet gray tanks are only like 10 gallons. I want to find the same depth tanks but wide and more gallons, I'm thinking 30 for the kitchen and 20 for the shower and bath, extreme water saving and two days in I can't drain my kitchen sinks because the tanks full is super frustrating, or what other solutions to this issue do you have? I have access to a 12v pump and was thinking of building a 50 gallon tank for the pickup and pumping these tanks from the trailer to the pick up. If we wasn't St horse shows I'd just open the tanks and forget about it but the trailer next to might not appropriate eggs and soap running in their camp haha.
  • I can't imagine trying to swap out tanks. It's very likely that the reason they are the size they are is due to space constraints.

    Have you looked into gray water totes? They range from small ones that you pull to big ones that you can attach to the back of your vehicle to roll to a dump station (or at least away from your neighbor :)).
  • Waste tanks

    Do your waste tanks connect and use a common drain header?

    If they do.........install another drain valve on common header.
    With it closed...you can equalize waste tanks by opening their drain valves.

    My galley is 28 gal but grey is 50. Galley gets full first so I just equalize to grey.
    Or to black.
    Whichever has less........

    I've toyed with the idea but most of the places we camp font have a close sewer dump, I've thought about putting a 50 gallon tank of the pickup, and pumping out to the pickup

    They don't I have three tanks and three clean outs, I've thought about combining the tanks and making 40 gallons out of the two.
  • Waste tank size is one of the most common underestimated items when purchasing an RV. It is silly how small many of them are.

    Yea I wish I would have bought this trailer new, it's a 2000 but the guy custom ordered it used it once and had a stroke, so we got a new trailer estenally.
  • The external tote will be your easiest upgrade. I believe you can go as big as 50, or more, gallons. Easy-peasy.
