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

To answer the subject line (how many 50 amp gassers) Many, mine included.

The subject of the post though seemed to have more to do with Inverters than 30/50 amp... This is a matter of cargo carrying capacity.. Gassers are often very short in CCC.. My rig for example can carry less than 1,000 pounds and a pair of GC-2 House batteries (or a 4D their 12 volt equivalent) is over 100 pounds (or 10% of my CCC) This is why they go light on the batteries in a Gasser,,, They simply can not carry all that lead.
