You said there was a 'capacity upgrade' in your original post.
No matter which svc you were talking about (either Sv 43 / 50),
there is still no such reason for your use of 'capacity upgrade'
words.
Because, when 2 x Sv 43 DDs are swapped for 2 x Sv 50 DDs, how is
that a capacity upgrade in any way? The most of us usually use
'capacity upgrade' those words only for SD to DD conversions /
rigids to Bendies or Enviro conversions yeah btw.
Yes, I mean an SD to DD conversion on 43.
2 x Sv 43 DDs were swapped for 2 x Sv 50 DDs. There was no
downgrade on 50.
So, why was there an upgrade on 43?
