If I want to run a 1500W/120V space heater (using shore power), is a 15amp short power inlet installed in van and a 15amp cord from van to camp shore outlet adequate? And maybe using a 250W appliance briefly at the same time (on separate breakers in van)? [font=Tahoma, Verdana, Arial, sans-serif]Campground shore power outlets typically are 15amp/30amp/50amp. All very confusing to me.[/font]
