Your cart is empty. This funnel is 2-3x larger than my Winterization or Sanitation funnel, and is still Hands Free!, turn and lock it on!
If your goal is to fill your tank from a water jug, bucket. This is about the biggest funnel that can be made and still be compact and affordable.
Takes the ENTIRE throat of the fill port on the rv. I can pour a gallon of water through it in about 13 seconds. (video coming shortly)
This was requested by multiple people. This will work much better for larger amounts of water or chemicals if needed.
If you don't need one this large, please look at my other smaller funnel in my store, or if using a garden hose, look for the fill adapter.
*NOTE: This funnel may have slight imperfections. Due to the design, multiple support structures are needed to print this. This is a limitation of 3d printing. It is aesthetic only, and in no way affects the performance of said item.

Bought this for a Forest River GeoPro and it fits on the water fill just right. I use it when I pour from a 5 gallon water jug into the fresh water tank. I used to have my wife hold a funnel but now she doesn't need to. It looks like it was made from a 3D printer, overall quality is good. I recommend it.

Makes treating the tank much easier. It's the little things that make life better camping.

Works great and looks spiffy too. 3D printed maybe.

Honestly... my tanks were installed aftermarket on my skoolie and my water fill is horizontal --- so I have to seal the holes and it took several attempts before I succeeded - then my dog ate the thing! For the price it's an obnoxious hack - but when I can't find a hookup this comes in clutch at any water bottle refill station. And keep these away from your doggos... evidently they're an expensive chew toy, as well.

Basin too small, fluids would splash out. Hands free is great, but basin should be a bit larger with curved up sides.

This is must for thos RV'ers who have small fresh water tanks and camp at State parks with no water hook ups. This gadget also makes it easier to winterize as well. In NYS, many state parks do not have water hook ups. You fill up before you park. We have a 26' camper. Sometimes by the time we back in and level...we have lost a bit of water and are taking jugs of water and a funnel to refil. This Gadget is welll worth the money. It does screw into your water intake outlet. You can take your hose our a plastic jug to the spigot to fill with water and just pour. Simple as that. I would vote this Product of the year so far!

This funnel works perfectly on our travel trailer (as shown above) and makes pouring liquids into the tank super easy. The seller was very helpful and communicative when we had a problem with the delivery by USPS and gave five star service to remedy the situation. Highly recommend this product.

The part fits the standard RV water tank inlet and orients funnel up. I previously using a carved out water bottle that worked OK but needed three hands to hold the funnel and balance the 7 gallon spigoted water bottle. The gripe I have is that the unit is 3D printed with no specifications. It would be nice to know exact material used and 3D process to determine health and environmental exposure limits. Not very professional to omit important information. I would not rebuy.
