We have had air filters replaced check the tire pressure constantly, and totally disappoint mileage-wise with this unit. Any ideas from the professionals?

It's not even broke in yet.

6 Mpg is not bad either!
My single axle peterbilt with a c7 cat gets 6 and it's only loaded half the time.

Hi Dave, it is actually small than our Gulfstream by only 2 feet. Not certain of the overall weight.

You can check the spark plugs/gap and coil packs too. Maybe a tuner to up the milage a bit but the V10 is no champ on the fuel. What motor did your last motor home have?

Hi Doc. The Gulfstream also had a V10. We will look into the other great ideas.

Another consideration is to use synthetic oil instead of conventional. I've changed all of my vehicles to synthetic (Amsoil is my favorite) and all got around 4-5 mpgs more.

Good luck!

I wouldn't expect much if any gains. Even if you improve it by 10%, that's still 6.6mpg. It's just part of RVing

Our '02 Georgetown 325 (F53/V10) gets a fairly consistent 7.5 mpg. That's a heck of an improvement over our previous rig, an '85 26' Class C with a carburated Ford 460. It got 6.2 mpg at sea level and less than 5 in the mountains. With this rig, fuel mileage doesn't vary with altitude, thanks to EFI.

We run fairly light - 2 people, two Labradors, no toad - and we're usually only out for 10 days, so there's not a lot of "stuff".

Why you all so worried about the mpg for your box on wheels get.
It is a house and weighs 4 or more time than a big SUV which gets 16mpg.
Drive it. Enjoy it and have some fun folks.
Gas prices are at a super low price these days.
I'm filling mine up and planning a week in Las Vegas.
Lets go!

Why don't you all run diesel engines, is a diesel nor offered? If my TV was a gas engine I'm sure I would be doing good to get 5 mpg towing 22,000 lbs counting the weight of our 5er and TV.
