If your permanent residence is located at high altitude, I'd probably stay at a 40HP or so for towing.
My reasons for recommending 40HP Towing are as follows:
1. No excessive over-fueling. Towing power will increase but will not dump unnecessary fuel into the engine.
2. No excessive over-fueling. Less fuel will require less air.
3. Mileage will increase over current 80 HP tune due to the reasons above.
