....and you my friend are special. 

143tas on 12gph isn’t great, but it isn’t bad. I can carry a lot and go a long way tooI walk away from them, too, on 9 gph . . . . .and I don't have but 180 hp . . . .
But I did get my HP endorsement in a 182. They aren't useless, just gas hogs.
Um, you know you signed me up for this forum, right? I still pop on here every so often.
I think I have a shopping spree in my future . . . .
I probably should work up a table like you did to see exactly what the cost is...
