Frame & tank mounting?

Hello All,

I received my grey tank (100 gallon) today and will be mounting under the bus.

I am considering mounting options and looking at existing holes in the frame. There are available holes spaced along the frame rails. See pic.

Between 1 and 3 holes are open at each location. There are holes spaced in such a way that I will have mounts at each end and in the middle.

I am thinking of bolting (grade 5+) flat stock to the sides of the frame rails to hang the tank cage.

What do you all think?

Makes sense to me. I'd be doing the same thing except the cage for my fuel tank is in the way, so I'm going to weld a piece of angle steel onto the cage to support the in side of the gray water tank.

The tank is 50"x26"x18".

The 26" width fits between the frame rails. The 50" length puts mounting points on the frame a roughly 0", 30" and 50"

I am so glad that I bought a bus with almost zero rust.

Are you going to add support across the bottom and abrasion resistant
material to the sides? IDK if you need it, but the poly propylene tanks I got bulge a bit. I used 16 gauge steel across the bottom of a 35 gallon tank and that helped, but probably could have been a bit more.

The tank will be nestled between my baggage bays so the sides of the tank are protected.

The bottom will be supported by a "ladder" sort of structure with the cross pieces made from 1" square tube spaced about every 12".

The tank will not be the lowest item under the bus. There are plenty of bus parts that will drag before the tank.
