30844 Barker Portable Waste Holding Tank 42 Gallon Tank

Missing parts, I had to contact the manufacturer to send me all the missing parts, apparently this is a common thing for the distributor to do, missing handle, missing all the caps

I also bought a short 90 degree fitting to direct the black water into the top tank. It's not really required with the hose that comes with it, but I felt it was more covenant. I would have like to see airless rear tires... but it was nothing big to get those inflated.

First time use today 12/07/2024 in Quartzsite, AZ BLM La Posa LTVA south. Pulled ok behind truck but when I stopped the bar popped off trailer ball, and popped off once over rough terrain moving at walking speed, but no big deal, still much easier than prepping / hooking up camper trailer just to empty waste & refill water. I removed top cap for best airflow, emptied fast. A youtube video recommends removing the wheel retainer caps, drilling holes in axles & using cotter pins.

easy to put together and works great. nice tires and heavy duty handle

been using this for half a year now and its okay. the original tires were kinda cracked and came apart after like the 2nd or 3rd time i used it, but harbor freight has plenty of replacements so not a huge deal. the tank itself is pretty solid thothe blade valve seems to leak slightly, but i only use it for dumping my showers so it's nbd to me. if i wanted to dump my galley or black tank i'd probably take it apart and inspect it first. it shouldn't really leak at all tho x.xthe arm is a little sus. it's held in by a pin with a captive ball bearing instead of a bolt or something, but it seems to do okay somehow. i usually use a cambuckle strap to help secure it onto a ball receiver so it doesn't try to fly off of there. it's best if you don't go too fast or too far with it, it's def not meant for much road use lolthe level gauge is kinda useless lol, it restricts air flow too much when you're filling it and opening it to have more flow makes it liable to just fly off from the air pressure xDoverall, it's okay and it gets the job done. this bad boi can fit like a week or two of showers so i don't have to gear up my whole house to take it to the dump as often. it fits my entire grey tank with some room to spare which isn't something other tote tanks can say.EDIT: coming up on one year now and destroyed that set of tires from the harbor freight lol. while trying to change the whole tire and rims out with a set of solid rubber ones i realized something that's kindof a pain: the way the wheels are held onto the axels is with a cap with slats cut in it that is set up in such a way to be really hard to take off. good for keeping the wheels on the axel, but not good for replacing them when needed. i think it would be better to have holes drilled into each end and just use a washer and cotter pin to make it easier to facilitate replacing the rims and tires easier when need be. going to make this modification (plus the solid tires, non-pneumatic) and see how that goes.been holding up okay otherwise! haven't even had the arm pin pop out like i thought it might.
