Default 454 TBI mpg

Looking at a 32' Winnebago for a decent price locally, it has a 454 TBI and 4L80E. I tow a 24' enclosed weighing about 8-8500 pounds. What rough MPG would I expect. My last one was 454 carb/th400 and I got 6 on good days. Looking for something a little more fuel friendly. Thanks
