Barker sewage tank mounted

This is my Christmas present! These were on sale for Black Friday so I asked for the biggest one! But the 42 gallons size is huge and too big for me to lift. The measurements say 24” wide but it’s actually 27” with the pneumatic tires.
I wanted to put it in the basement but even the next smaller size at 32 gallons was 27” wide. I thought about mounting it on a hitch rack but did not want it in the way of the rear door. So I found a bumper mount. I ordered the Camco Mount even though there are cheaper versions and I’m happy with the sturdiness.

The bottom plates are 1/4” steel. I have a bolted on 1/4” steel bumper that was installed by the previous owner. It’s really tough.

I have been RVing for years and never needed one of these but we always took shorter trips and we are planning to take longer ones this year. Plus we will be parked for two full weeks and don’t want to break down to dump. So splurge!
  • At 47 pounds dry plus the rack on your rear bumper and without reinforcement, I’d be concerned.
  • I'm getting that bumper rack, too. I'm at Imperial Dam LTVA for the winter, so got a 28 gal Camco, since my tanks are 25 gal each. Grey lasts a week, black 2 weeks. Much easier than breaking down camp and towing the trailer over.

    I had to return the 47 lb tank. I could not lift it! I bought the 32 gallon size that weighs 37 lbs. The bumper is custom. The PO told me when they replaced it the shop told them it was better and cheaper if they built a steel one. It is very heavy duty and bolted on securely. So I’m not concerned. Except I need to get weighed for our trip. I don’t want to overload the chassis. It’s probably easy to do with the huge basement in this rig.
  • Gray is 26 gal. Black is 21. So 45 gallon made the most sense but I could not handle it myself.
  • Good luck with it, I wish I got a better one. I think I have a camco one, used 1 time. Got for a trip last minute and was the only one I could get. Those are supost to be top on the line. I have a 15 or so gallon one when I had the pop up. It was well used and never a problem. Add some paper plates into the mix, hopefully a confet statuon for showers, and depending on how long your stay is, dump some gray in the black tank. Lol. You'll get it. Good luck with it!

    It'll take a while to fill up your black tank. How long do you usually stay out camping?
  • We plan to be out about 4 weeks. Will be parked at least 2 weeks at a single spot that is why I don't want to move the RV. We are even renting a car there. We have never camped two weeks in one park. So I may be over thinking the need for waste. Lots of people have these tanks and they seem to use them in cases like this.

    You've got the right idea. Your black tank could last the full 2 weeks.
    DEpending on size of tank. But it's unlikely your grey will go more than a few days depending on conservation.
    Either way have a large tote allows you 2 dump whenever required without breaking camp.
    More than once I have brought tote along and not needed it, but it provides peace f mind to have it along.
    No need to worry if/when tanks are getting full.
    No need to conserve unless you want to.
    Having the tote means that if you have ample fresh water you will always have the ability to dump waste water as required.
