National park trip; MPG Est??

I am the proud owner of a new-to-us Holiday Rambler, 2000 V10, class A, F53 chassis, 285hp (before the engine upgrade per serial#'s). We enjoyed our 36' 5th wheel for some ten years but decided towing a 16000# unit with a 3/4 ford diesel over some 2,000 miles of Rockies might be a problem. So we bought this unit.

Here is my question: I know one cannot do much to improve the performance of the v10. We have installed the Banks ram air intake, the 5 star engine tuner and AMSOIL in both the engine and transmission (my previous experiences with each having been exceptional).

I have NOT driven the unit (47,400 miles on the OD) enough to get a good handle on MPG but it seems to be about 6.3mpg (before mods). My question, we are going to head for the rockies (5,400miles est), towing a Santa Fe on a Demco KK360SB unit (i'm also worried about grades/braking but understand this is a GREAT tow dolly).

What milage can I expect? As our trip will be some 5,400 est miles, anything I can do to improve MPG is important as at 6mprg thats 900 gals or $3,100).
PS...this is our long dreamed of 20th anniversary present from us to us.
Thankls for any advice/comments.

Just be easy with your foot.

You ARE going, so the MPG will be whatever.

Fill-er-up and have a grand adventure.

keep it under 60 to maximize mileage. I want to yellowstone from Oregon last year and mileage ranged from 8.5 to 10.5. I get about 1 mpg better keeping under 60 mph. That extra $100 in savings was worth it to me.

Joe--I'm afraid a Class A gasser in the mountains with a toad is not going to be exactly fuel-efficient. You will likely average 5-7 MPG, but that's just a guess on my part based on our experience. Slow down and enjoy the scenery, and have a great trip.

Happy anniversary!

As others have said , take it as easy as you can on the pedal. The harder you press it , the sooner you'll have to visit the man with the Texaco Star . Have fun , enjoy.

Stay at about 2000 RPM or the speed that "feels" best. I suspect you should average ~6-6.5MPG. Let us know.

Just remember. What MPG does your current house get?

I get a pretty consistent 7.5 mpg with my '99 V10. I tow a 3500 lb enclosed trailer, run about 60 - 62mph and have the 5 Star tune. Now this is running between Mi and Fl. You won't get that going up into the mountains, but you'll make up for that coming back down . Keep the speed down, travel light and keep the tires properly inflated, that's about all you can do. Enjoy the trip!

We went out west in 2008 and 2009. In 2008 we averaged 8.33. In 2009 we averaged 8.32. I also went with the Banks air intake. I did install a stainless flow through muffler also. I kept the rpms at 4000 uphill.(light on the throttle) We kept it at 58 mph on the flats. This is with a 35 foot Pace Arrow and pulling a Honda Civic. We went all through the rockies and visited all the major parks. I never felt power was a problem. The V10 is a great engine. You will get tired of the engine noise,(pulling hills) but keep it at 4000 rpm and it is not too bad.

First trip to Rockies

Our thanks to all. The concensus appears to be:
keep it at 60mpg
keep rpm's around 2000
keep hill rpm at around 4000
Engine noise will be loud
Banks Ram Air and 5 Star tune were good choices.

Greatly appreciate the input. Makes both financial and driving decisions and expectation much easier to calculate.

You forgot two more. Take your time and see everything and take lots of pictures.
