CARB Certified. With its built-in versatility of dual-fuel at 1,800 running watts, and portability at under 40 LBS, this by itself is already a great consumer product. The fact that it also contained a 30-amp plug-in outlet, provided a practical option for any RV user staying off the grid. Good stuff; nicely designed all around!
After being so satisfied with our 4500df we opted to purchase this second Westinghouse 2550df for the versatility that it offers. It's lighter than we thought it would be which is great and the dual fuel feature is awesome. Currently breaking it in on propane and it's running perfectly as expected.
