Dimensions & Specifications:

Designed for the Ford Transit, all wheelbases.
Compatible as an interior water tank, for any van. 

This tank can be mounted on the PASSENGER SIDE or DRIVER SIDE of your van. PLEASE NOTE that our Aluminum strapping kit is compatible with the PASSENGER SIDE ONLY. If you want to mount this tank on the driver side, we suggest using Aluminum or galvanized steel-slotted strapping with 1/4" riv-nuts to secure the tank to your van's undercarriage. Only use corrosion-resistant strapping, as the strapping will be exposed to moisture. Alternatively, please check out our Transit 17 Gallon Undermount Water Tank and strapping kit which is designed for the driver side. 

The end of the tank with the 4x fittings (1 x 1 ¼", 1 x ¾", and 2 x ½") usually faces the rear of van, but the tank can be faced in either direction

Tanks are made from linear low-density polyethylene.
Food grade CSA approved and BPA free - safe for freshwater use!

    Dog approved
    Size: 3.5" (Medium/Large Dog), Color: Set of 6
    My 60lb 11mo puppy loves these balls! They do get a little softer the more she plays with them but they are light and squeezy enough for fun retrieve, catch, bounce and training. AND does not break things in the house since they are fairly squeezable. The sqeeky can be a little loud but it also helps get her attention and she is so excited to play with multiple ones. I'm also suspecting the plastic spikes may even help clean her teeth. They are the perfect size for a German shepherd. This multi-pack is great to have to use some outdoor, indoor, and i replace old ones after my pup gets them too dirty to wash.

    The dogs favorite toys!
    Size: 3.5" (Medium/Large Dog), Color: Set of 6
    I have 3 German Shepherds. These balls are their favorite! They live to have me throw them and they love to chase them. They are outside toys, but they always try and sneak them in. I have purchased these quite a few times because they love them. The balls squeak and are soft enough for me to squeeze them, but tough enough that they don’t go right through them. When the squeaker dies, they still love to play with the balls until their squeezing finally breaks the ball. Remember they are outside balls, so they are in all kinds of weather. We do have other balls, but they don’t play them.

    They bounce and float
    Size: 4.5"(Large Dog), Color: Set of 6
    Perfect size for my 65 pound doggie. They bounce just right, float, and they have a good squeak. The spikes are larger than those from other brands, not an issue for me, but the only sign difference I could see.

    Spiked Ball = No Slime!! ☺️
    Size: 2.5" (Small Dog), Color: Blue+Orange+Green
    You will lose these balls before your dog could destroy them. Very sturdy for the price. The spikey ball style means your hands won’t get slimed when your dog drools on the ball playing fetch. Great fun colors.

    Durable but to hard to chew to make squeak.
    Size: 2.5" (Small Dog), Color: Pink+Red+Yellow
    Nice and squeaky but a little too hard for my 25# Cockers to chew on...may be the spikes.
