    Definitely use 1/4" 6061 plate, NO smaller. I would also use 3 baffles. Weld it with 1/8" 4043 filler rod.

    Thickness could depend on what you have in the way of metal bending stuff.
    If all you can do is just make it slab sided then thicker would be better.
    Baffles can be very tricky to weld in with a tig. They will need "feet" made on them. Good design will help a bunch. I have seen baffles busted loose in big boat gas tanks.
    I would use 5052 for this because it is designed for corrosion resistance unless someone here has a better reason. All sorts of fuel tanks are made with this as well as most fresh water boats. Then you could also use 5356 filler.
    5086 could be a better choice for material as well. It has even better chemical resistance properties. Not sure if you would use any additives in this application. I barely know my job it seems at times.
    I would spend some time thinking about which hardness also.
    You could re-enforce the corners with angle and even weld ribs to the sides and make the bottom so it was forkable.

    Still in the talking stage. The customer has been busy and I have been to.

    I was at his place last night, still on the fence.

    Yea I know all about that kinda stuff. Sounds like you might wanna find a way to make it fit his budget and still be nice.
    Ordering the metal already cut to size and bent into 2 channel shapes so it all fits together helps me get the price down. You could use 5052 H-14 and then weld a rib around the perimeter. Maybe use a couple of pieces of channel on the bottom as well.
    You do need a spoolgun for this tho (in a few key spots) IMO. Otherwise you will need to give a ton of thought about the assembly sequence. Or the design. The baffles can be tricky to weld to the slab sides when the metal grows all funky shaped. Clamping and tacking is very important here.
    Knowing when to stop welding and cut stuff back apart is a thing you learn from exp. I can tell now much sooner when bad stuff is gonna happen than say 10 years back

    You are a wealth of information. I gotta say I am kinda nervous about this, but I am sure I can do it.

    Yes a spool gun would be nice I am looking for one.

    Smile You can . . .

    You can buy a plastic tank with a steel wire cage for far less than you will ever build that tank . . .

    Yes, I know. I just purchased a 375 gallon plastic tote for hydraulic oil for $175.

    The customer wants it made out of aluminum and a specific shape to make the best use out of the room in the box truck.
    There is no doubt that this will be expensive.
