We have a Champion 2500, not dual fuel, they were not available when we bought ours. I think not worth changing if I still need a separate fuel source. Taking a 1gal gas can along has not been a big inconvenience.
@NovaTab funny you mentioned Champion. I was browsing the Home Depot website and found a nice dual fuel 2000 watt Champion. It's more than I want to spend but I'll try to rationalize the cost as it could pull double duty at home during a power outage.
Thank you for all of your comments. I’ll take a look at the Champion dual fuel generator. I’ve also submitted a request to join the T@B Facebook Camping group so I can read the review on the on the Alp. Does anyone have a comment regarding the electrical hookup to the 400? I’m assuming I can connect a 15 or 20 amp dog bone…
