Be careful about welded 6061 for chassis construction - the strength in the heat affected zone (within about 1 inch of the weld) reduces to about 14 ksi because it loses it's temper. 5456 and 5086 are better choices if strength is a concern - they only lose a couple ksi as-welded - but they're a little harder to weld because they're not as ductile.
