Recently purchased a Hutch Mountain propane conversion kit for one of our two Honda gens. Anxious to install and gauge performance. Used one of two gens during a trip to Grand Canyon this past summer. Camping at higher elevations we found we did not need the 2nd gen since no A/C was necessary. We also use our gens as backup power for our home. We can run critical home circuits on one gen. Being able to tap into our 400 gallon propane heating supply makes this very handy for extended power outages. Following an ice storm in 2005 some customers in our area of the Ozarks were without power for more than 10 days. Not fun in the winter. We got a deal on a two gen package from someone who purchased them for a short time and then decided to buy into larger 5th wheeler. I have been very happy with the Honda's and do not regret the investment for the long haul. You will not regret your choice of the little Honda.
UPDATE: installed the propane conversion kit. Nice and easy and works good. We can run the 13.5 A/C unit with one Honda running on gasoline. NOT so running the generator on propane. It lugs down and voltage drops for an extended period. I did not want to run the A/C on the low voltage to see if it would finally start. We are at 1200 feet elevation.
