Hello everyone, happy to join the experts. I am in the process of purchasing a 1999 Tioga 31 footer with 450 10 valve engine and I'm concerned about the gas mileage. Greatly appreciate feedback. Than...
Motorhomes push a lot of air. If it hurts when you calculate MPG, stop doing that. A MH wouldn't get good mileage if it fell out of a tree. If you want to get better mileage, drive expressways. In the right hand lane. Slow down to the posted minimum. You'll never have to pass anybody and your mileage will be as good as it gets - lousy. An added benefit: You'll never have to pass a semi except on long uphills.
