I just ordered a new Toy Hauler. I'm curious what size generator to use to be able to run the AC on the hauler? I'm hearing lots of things,,anywhere from 2k up to 4500 is needed.
What have some of you used to make yours run? I'm trying to stay away from the Honda and Yamaha due to their price. I also want a quiet running one. I see some chinese knock offs for around 500 bucks. I've heard from a few people that they work well. I also want it to be the digital style inverter generator.
You need to add up the appliances you want to run then buy accordingly.
Normally RV campgrounds provide either a 15a or a 30a hooked.
Calculate into wattages and you get 15*120= 1800watts or 3600w for 30a service.
Anything with a heating element takes a wicked amount of power.
an average AC take 1800 watts +/- alone when running and maybe 3600watts on startup depending on quality and condition of the AC.
Anything that takes a startup draw > running wattage needs to be considered so a 1800w electric motor may need 3600w to fire up so if you need to keep some wattage in reserve if you are firing up stuff with a higher startup draw.
So the math is wattage = amps * volts
(wattage = amps * 120)
So do a survey of what you want to run. They will almost have an amp or wattage numbers on them then IMHO add 50% for startup concerns.
