Absolutely Wayne.. And the OP has a 3500W constant speed generator to use for battery charging. This is much larger than necessary to do the job and as a result, uses much more fuel. According to the published figures, the Champion 3500W uses over 1 gal per hour at 50% load and the Honda gets 15 hours on 1.1 gal at 1/4 load.

Yes, my Honda is only running at about 1/4 load when battery charging, even at bulk charge rates with my PD9260. The Champ 3500 would be at less than 1/2 load, but I was unable to find any other consumption specs for it. Greengreen says less than 1 gal per hour, but still that does not compare to less than 1/10 gal per hour.

One thing brought out on this string was the importance of adding solar to the system if you are a long term boondocker, and the need to fully charge the batteries at regular intervals to avoid sulfating.. Personally I keep my TT plugged in when it is stored, so this is not a problem.

Great information here though...
