The next inverter for you is this model from Power TechOn. Stupid name admittedly but another very well designed, high end product. This is the third RV inverter in a row to make our list that is a True Sine Wave inverter style.
This is also a very powerful model, capable of generating 3000 Watts continuous and 6000 Watts peak power. That is a level of electrical power suitable for even the most power hungry RV set up. It also comes with very sturdy ring style battery connectors and a remote switch with a nice long connector cord.
