As GENERAL statement, one can tell if a gas coach (gasser) has 30 AMP or 50 AMP service. ONE a/c on the roof = 30AMP.....TWO a/c on the roof = 50 AMP.
Exceptions, of course.
My coach (2001 gasser) is 50 AMP with one "27 Series" 12V starter battery and 2 6V (GC-2) in series for the coach. Mine came with 19.5" tires, some of the newer Ford gasser coaches come with 22.5" tires. With my 19.5" tires, over the years, I've noticed (on the sidewalls) the weight carry capabilities has increased, to respond to, I guess, the increased weight of gasser coaches.
Mine is a F-53 with a 20,500 pound chassis.
FWIW.
