We have had 2 C's and 2A's.  I was always frustrated by the very limited view from the front seat of the C's.  Woith the A  you sit a little higher and have a great view.  The one disadvantage is you may need a little s unscreen once in a  while.  Most C's are now  widebody and are the same width as the A's.  With the A you  are sitting over the front wheel so  there is a little bit of adjustment to making turns on tight corners but that is easy to get used to.  My first C was a Dodge 360 on a '76 chassis, 2nd was an '89 E350 with a 460, 3rd. was a 35' P30 with a 454 and current is a 38' on a Workhorse W22.  With each MH the MPG has improved, going from 5 to 6.5, 7.5 and now 8.7 on the current one.  Most of  those differences have come from engine improvements.
