While the number & letter combinations can sometimes
help, other times you'll find codes like 'EXP X213'.
We decided long ago that the combinations were invented by the marketing
department to force prospective buyers to...
1) read the brochures marketing prints and
2) return to the dealer to try to make sense of the notes they made.
Within the different models
, the codes are usually somewhat consistent. Between various models they can be close, but there can be significant differences.
One example (and I'm sure there are MANY others) the White Hawk 27 RLDS and the Jay Flight 27RLS. The codes are very similar, but if you read the literature you'll find major differences.
I'd like to think this helped, but...
'We are as confused as ever, but at a higher level about more important things.' may sum it up.
