I looked at my tanks. They have stamped on the tank around the fill nozzle....
"Fill to no more than 40 US Gallons." on the right side and 34 on the left.
Then underneath that is states...
"95% Liquid Capacity"
So, the old question is, 95% of 74 gallons? Or is 74 gallons equal to 95% and thus the terminology "Fill to no more than 40 US Gallons"?
So worse case Math logic here is....
74 gallon x 95% x 6mpg = 422 miles
7mpg would equate to 492 miles
One question I have: Will the generator cut off at 25% tank capacity?
I had this on another Motorhome send had it happen to me but I haven't seen anything documenting that on the Seneca.
