The Kipor 3000ti is one of the quietest and economical gas generators. It's lightweight and easy to operate. I use it with my 29 foot travel trailer and sailboat. The gas genset is very quiet, easy to start, has a smart throttle and is an excellent battery charger. So far I've had no maintenance problems. I've used this on camping trips and it sips gas, lasting much longer than the 4 hours suggested. I would buy another one.
