30 amp VS 50 amp

[bubblerboy64]

Thanks for the information on this subject. The ONAN is rated at
6500 watts not 8500. I would think if all is well it should handle
the two air conditioners. I'll have to consider the conversion to 50
amp service. I was not aware that 6 gauge wire for shore power was
available. And here I thought 10 gaurge large. JOhn Heckman
