Copper is not a good choice for some water chemistry. I know it’s not allowed here for houses on well water, as the water will corrode it pretty quickly.

I can remember when trucking industry used copper for air lines; From that experience I would not want to use for water on a vehicle.
And can't understand why use for propane lines.

Best bet would be to replace it with pex line. It rigid yet flexible.

Unless the tank has been struck or damaged somehow the problem is seldom the tank, but more often the associated plumbing, like valves , nipples and fittings.

My ‘18 the tank was fixed twice and leaks again now have to tear it apart and see why I flooded the lot the last night we used it Dan

It ran completely dry dry fast so I doubt that it is piping.
I know I’ll be smarter when I have the panels off.
My question was about using aluminum to build another one. I thought perhaps that would be ok since the hot water tanks are aluminum.
Plus the benefit of having a bigger one.

I suggest dropping the underbody and seeing what's going on before you order an expensive tank that may not the problem.

This is good advice. You don't know that the problem is the tank itself.
Problem could be a fitting or piping leak.

gee mines 17years old still going strong, might be a broken line etc.
