We have ran ours all night without an issue. Now that I've installed 520 watts of Solar and 435ah battery bank and TSW inverter we haven't had to use Genny anymore just yet.. While your camped at Walley World go inside and buy a CO detector and sit it anywhere in your RV you want for protection from carbon monoxide. They hold 1or 2 AA batteries.
