I have a onda EU3000IS and I love it.Just got back from the past weekend Deer Hunting. It is quiet and I ran it over 7 hurs without filling it up. I still have gas in it.
Holds 3.4 gallons I believe...Amazing....Wasn't running the A/c the whole time, though. I was watching TV and Movies between hunts. I was running on Eco Mode.
If the weight is not an issue....Less filling of gens if your debating foing with 2. Also fill it up and you already have 3.4 gallons ahead,..then bring a spare gas can.
