The Yamaha EF3000iS is an excellent choice for people who want to use their generator to power electrical equipment when camping or traveling in an RV. The fuel efficiency is remarkable, as it can run for up to 19 hours on a full tank at a 25% load. The noise level is also quite low, at just 53 decibels from roughly 23 feet away. This makes it ideal for use in areas where noise levels are a concern. The biggest negative about this grill is that it is rather hefty, weighing in at 136 pounds without gas. However, it does have four wheels to assist with the weight.
