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!

    Comfortable and complimentary
    Size: 11, Color: Brown
    The shoes are very comfortable and easily broke in after two wears. I get several compliments on them daily, and others have purchased them after seeing mine. I also have the black pair, but the brown ones are my favorite. Sizing is true to size, an excellent value for your money, and they are lightweight and breathable. The soles are thick, which makes them extremely comfortable.

    Comfy and non slip! Amazing!
    Size: 9.5, Color: All Black
    I work 12hrs sometimes on my feet. These shoes are amazing !!! Broke them in on a 10hr shift and they feel like walking on pillows. My feet were comfy and not throbbing. I felt the difference in the non slip in the kitchen and I’ll say it outright……. Worth the $40! I got the brown coming and I’m assuming they’ll be just as comfortable. Bruno Marc’s are great!

    Nice but not ideal sizing.
    These look nice. They do not have a traditional tongue, replacing it with some sort of elastic lining. They do fit larger than expected. I purchased wide since normally need that and it creates a bump just below the laces. Also, after size 11 there are only whole size increases. I feel an 11.5 regular would have fit better. They are pretty comfortable with a cushiony insole and thick sole.

    Slip ons worth slipping on…
    Size: 9.5, Color: Black, Size: 9.5, Color: Black
    Very stylish and comfortable. I love how light they are because I’m on my feet all day. The black leather is very deep and very rich. The elevated sole gives me a tad more height, too…which I like. And yes, they’re slip ons. Don’t let the laces fool you. For under $40, these shoes are a strong value to consider…

    I feel I’m walking on clouds
    Size: 10, Color: Brown
    I’m on my feet 6–8 hours a day working at the dealership, constantly walking the lot and helping customers—and I’ve gone through a lot of shoes trying to find something that actually holds up. These Bruno Marc MaxFlex Dress Sneakers honestly surprised me. They look sharp and professional enough for work, but feel more like a comfortable athletic shoe than a stiff dress shoe. From day one, there was no break-in period, no soreness, just all-day comfort. I feel I’m walking on clouds! If you’re in a job where you’re standing or moving around a lot but still need to look polished, these are hands down the most comfortable work shoes I’ve owned.
