Take the money you would use in an attempt to improve the fuel milage and buy fuel with it. The miles driven increase/dollar spent will be much greater.

Lots of people swear by Air Tabs and they're not that expensive. They're on my wish list....

I have a banks system cold air induction and exhaust the good thing is it was all installed by the po so no money out of my pocket but my milage is about what yours is 33' allegro bus 454 big block. the heaveier the left foot the worse it gets. Try to find a sweet spot where it runs good no matter what the milage . Avoid head winds and interstate speeds for best results. Is a flat faced big heavy rig with absolutely no areo dynamics so slow down and enjoy the trip.

2011 Allegro 32BA with a Ford V-10. I would be happy with 8 MPG. Best we have ever got was 6.9 MPG. That includes towing and running the generator.

Early last spring we made a visit to southern Az. from Utah. Without the toad we averaged about 9 mpg. 92 HR with banks etc. Kept the speed as close to 60 mph as possible for the entire 1700 mile round trip. Later this summer WE motored with the toad, a 2400 lb. Tracker, to the Or. coast. Down the Columbia river to Longview, crossed the river again to Astoria, south to Newport overnighting in CLEAN state parks. Returned through Portland, up the river to Pendelton and home. On this trip of 1600 miles at 60 mph we were able to average about 8 mpg. As many have stated DON'T drive like a teenager whose father bought those cheap tires on the family car that only lasted a few thousand miles.

I pull a toad when we travel. That way I get TWO vehicles from A to B, thus doubling my mileage.

It's geat to read the responses. Everyone is quick with mileage but when you read between the lines there are difference in length, weight and engines. How can you compare mileage achieved with a 32 footer, or 5er to a 35 foot motor home.
Happy travel set back and enjoy the view.

Bottom line, with VERY few exceptions:

Cummins B or Caterpillar 3116 in a reasonably lightweight coach 10 MPG

Cummins C, pre-emissions in reasonably lightweight coach 9 MPG if driven conservatively.

Newer, heavier, higher HP diesels 7-8 MPG

Older gas coaches 6-7 MPG

Lighter newer gas coaches 7-9 MPG

Newer heavier gas coaches 7-8 MPG

We have averaged 11.3 MPG, logging every gallon of diesel and on calibrated speedometer for 130,000+ miles. Yes, it is "tweeked" and cruise at 60 MPH.

Let me share some actual experience with items installed you actually queried.
I had a W-22 Workhorse and 5 speed Allison.
About 8 MPG and driving habits seemed to have little effect on mileage.
I added a Banks system and along with that the change to an oil type full flow airfilter.
I had a definite increase in hp. Chirp the tires in two gears (that might be an exaggeration) But: it did run and perform much better.
I had absolutely no change in fuel mileage. Save your money and study your driving habits and make sure your MH and toad are tuned and tires at recommended pressure.
