How many GAS coaches out there with "50 amp service"?

[FIRE_UP]

Gang,
There are various threads being discussed here and there, concerning battery charging while driving, while plugged in, generator running and all that. Many of these issues are dealt with differently, on not only different brand/make and model coaches but, different chassis and engine systems ones too.

As I understand things, about 99% of the diesel pushers out there, are equipped with or, I should say come equipped with from the factory, with a larger house battery bank and, an "Inverter/Charger".

While most GAS coaches come from the factory equipped with a "Converter/Charger" and, a smaller setup for house batteries.

As with just about anything, there are most likely, exceptions to the basic "rules" I just stated. And, I've not done any actual research on the net or, any other potential source of info to find out more. I just thought I'd ask folks on here, ACTUAL OWNERS if they have one or, are aware of any GAS coaches, that come from the factory with a 50A shore power cord and, a larger house battery bank, i.e. at least two or four, 6V deep cycle batteries or, at a minimum of two, 12V deep cycle/marine house batteries.

I know there's "Heavy duty" Gas coaches out there that are running the larger 22.5" tires and wheels which, most likely also means that the frames, chassis, front and rear suspensions are of higher ratings too. Some of those I might assume, are rated in GVW that are very close to some of the lighter Diesel versions out there. I say "Lighter" meaning not the ones with tag axles and, ratings of say, oh, around 35K and up.

And, since those ultra heavy duty gas coaches have traits of the diesel versions, I was wondering if, those traits carried on with a 50A shore power setup and, a larger battery bank???? Thanks for reading.

It has an EMS system that allows both AC's to run on 30 amp service. When you go over the 30 amp threshold, the rear AC drops out until the amp draw falls back to allow both AC's to run. Also, it may be a load shed EMS system that ONLY kicks out the rear AC compressor and allows the Fan to run to help circulate cold air thruout. Can you tell if it has RVP(Coleman) AC units or Dometic? A/S usually used Dometic. But, RVP has a line of LOW amp Roof AC units designed for 30 amp service RV's that only pull about 9 to 11 amps EACH. Doug

My "antique" 1997 Winnebago Vectra came equiped with 50 amp service, and converter/charger and two 12V house batteries. this has proved to be a very servicable setup for us.

Our Bounder came with (standard) 2 6V house batteries (additional chassis battery), a 1200W inverter/charger, 50A power, 5.5K generator, 2 a/cs, and a power management system. We added 2 6V batteries and 600W solar.

The newer ones with residential refrigerators have an additional inverter and batteries.

Our 2001 Winnebago Adventurer had a 50 amp service as an option. Our 2013 Adventurer came with it as standard equipment. With the advent of residential refrigerators most middle of the road and higher end gas coaches have a minimum of 3-12 volt deep cycle batteries and a 2000 watt inverter/charger.

For 2015 (last year for full brochure available) the the Adventurer, Sightseer, and Vista lines of Winnebago motorhomes, and the Itasca Suncruiser, Sunova,and Sunstar lines have 50 amp services. They also have either 3 or 4-12 volt deep cycle batteries, and a 2000 watt inverter/charger.

I have a 1996 gas MH and it has 50 amp service, 2 AC's and a slide. I thought they all were that way until I started looking for newer MH's.

Almost all Class A motorhomes(Diesel and Gas) have been equipped with 50 amp service for at least 20 years. 50 amp service is used NOT because of the Inverter/Charger or Power Converter systems. They are used because of having 2 or more Roof AC units and the multitude of optional(now almost standard) of home type appliances like Convection microwaves and washer dryers. You will find that NONE of the Diesels in that past 20 years will have 30 amp service. The Class A Gas rigs you find with 30 amp(even now) are smaller entry level type motorhomes, that they use as a price cut to get a lower retail price. Years ago (more than 20) you were hard pressed to find a lot of CG's with 50 amp service, so having 50 amp was a problem when 50 amp service was hard to find. As of just 10 years ago, the RV industry was talking about starting 100 amp service Motorhomes. That idea has not gone forward. Doug

A LOT. Any new coach with 2AC's is 50A.

2013 Tiffin Allegro 36LA, 50 amp, 2 T-105, Tripp Lite RV750ULHW inverter/charger. There are upgrade options.

As far back as 2003 the Safari line of gas coaches came with 50 amp service and the Xantrex inverter/charger as standard equipment as well as a bank of four batteries for the house. ONE AC unit on the roof.
Monaco and Holiday Rambler also had 50 amp service as standard on some gas units as far back as 2000 with inverter/chargers. Size of the tires did not matter nor did the number of AC units.
I believe that those RV's with the Workhorse P chassis came with 30 amp service and that all of those on the W series chassis had 50 amp service.

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.

My 2006 gas coach was factory build with 50 amp service and room for multiple batteries. I have 2 GC2 batteries for the occasional need when off the grid but I could fit four if I reconfigure the battery tray. The demand for front and rear AC is driving the 50 amp need. The rear AC in my coach the first owner installed. I don't recall seeing a gas rig with a residential fridge which would drive a need for a bigger bank but I haven't been looking either.

For the past couple of years Ford has been using 22.5" tires on the 22, 24 and 26K lbs. GVWR chassis. Leaves 16, 18 and 20.5 lbs. chassis with 19.5" tires. Suspect the size increase wasn't so much consumer demand but to better match the load capacity of the axles. My 18K GVWR chassis has more load capacity in the 19.5" tires than the axles.

My 07 Bounder has 50A Service. It has convertor/charger

[FIRE_UP]

Well,
How about that. I learn something every day. Now I have a better understanding of how things are equipped. Now, one of you stated that he doesn't have an "Inverter" to go along with the 50A service. Could this mean that most of the 50A serviced Class A Gas coaches come with a "Converter/Charger"? and not an Inverter/Charger or, would it be a mixed bag, some with an Inverter and some with a Converter???

Agree with others. I have not seen any late model class A gas coaches that did not have 50A system. All had at least two batteries, also, generally two GC2 size 6V golf cart type batteries for the house. Generally, a well designed motor home will have two air conditioners if it is more than 30' as it takes additional cooling to handle the increased space. Shorter coaches with one AC would probably get along reasonably well on 30A service.
