On trips to shows we typically travel at 65 to 70 mph and am currently almost to the floor at times.
On the floor at about 1,900 rpm will it accelerate?
If not you probably need lower gears, that's a pretty low cruising RPM.
2,500 rpm at 75, your last combination, sounds about right.
You'll also get better fuel mileage with it geared right. You don't want to lug the engine. When you put your foot down it should accelerate, if it does not you either have it geared to fast, or you just plain ran out of power for the speed you're traveling.
What's your best guess on gear ratios considering how it drives now, and how you want it to drive?
