Assuming you use something like 6061-T6, the weld areas will eventually
age harden to about 6061-T4.

Not likely unless the entire frame is solution annealed first.

Actually, any 6061T6 weldment WILL eventually age to T4.
However, aluminum is NOT the material of choice for a jeep frame. ANY
deflection in aluminum is a cumulative stress, and the frame WILL
eventually fale from flexing.

Go with steel, hot dipped, or perhaps stainless.
Acid dipped and then hot dip galvanized will coat inside and outside.
I'd sand blast first, particularly the weldments, to be sure the zink
will get a good adhesion to the steel.
