I do exactly the same thing. We travel with the weather but want the option of running the ac IF we get caught in the heat. We have a remote start Honda EU3000SI bolted in the truck bed and covered with an 12 gauge metal ventilated box. ac 13,500 and also use it for the hairdryer and microwave. 520 watts/bogart/trimetric for the four gc2 batteries.
I have also repaired Honda equipment in a dealership and owned their motorcycles and lawn equipment. If I wanted to be able to take a product to the dealer and get it fixed I would buy Honda first because there are more dealers and then Yamaha. Yamaha is also an excellent product.
When the power would go out and 40 generators would show up at our shop very few would be Honda or Yamaha. An example of their quality is even seen in the ability of the metal used in their carburetors to withstand stale fuel. It's not that they cant have stale fuel issues but they seemed to tolerate it better than the others.
