......we averaged 6mpg on our trip.

1367_345:

I feel your pain, but I'm glad to know some actual numbers!

I've had so many people bragging about 10's and 12's I was beginning to think I had a seriously sick 454.

Anyone else have some documented numbers?

My numbers ran 6.5 - 8 mpg while I tracked it. It varied based on speed and gen set usage. Most of my driving was in Florida and Georgia. Mine is all stock.

I am averaging 7-9 MPG with a 2300 LB toad in Fla. If I run the genset it is more like 7. It really seems to be based on the speed more than load. This one rides so smooth I have to watch that I don't go too fast. I normally drive at 62-68 MPH.

Stock exaust, but a nascar-ed fresh air intake and a new Edelbrock Qjet carb. I am still tweaking the carb, the OEM carb got me closer to 10 MPG, but that was without the toad.

Headers make a big difference in milage and performance. I don't have such exact mumbers but I believe I'm getting about 20% better milage and alot more power.

my 76 Argosy had headers and I had more power for sure, the mileage with the same model Qjet was closer to 10, I know on our longest trip to Virgina I got close to 11 with no genset or dash AC required!

I also think that the timing on my 78 is off a bit, I just can't get it to perform like I "feel" it should and I know that will affect the overall mileage.

I'd be curious what sort of fuel economy some of the Isuzu and Cummins (conversions) diesels are seeing.

Happy Trails!!!!

My only mods are the tornado ar manager over the carb. The carb is stock but kept clean as i can keep it... I run mid-grade gas mostly, I put in Marvel Mystery Oil once in a few tanks...(a favorite of my dad who was a car man for years)

My exhaust is stock, except neweroem type mufflers added by Merlin Muffler. Dual exhaust with manifolds.
Tuned and new spark plug wires. I like Brett get 7-9 towing my Saturn running the generator for summer a/c.

I would like to get MSD ignition parts, and maybe a freer flow exhaust down the road...like Hedman or something.
Meanwhile I'm happy...the rig runs well and has been quite dependable.

Did I ever mention the jacobs ignition system????
On our big trip last summer, I averaged 8 mpg. I noticed a considerable increase in fuel consumption with speeds over 65mph.

i get about 8 when im not getting my foot in the tank and when i do mpg dropps to six . which is not bad, i pull a trail blazer LTZ that weighs more than i had planned to pull. but it pulls it with no problems. i dont think 7mpg is a bad figure for a gas mh pulling a toad or anything. the new fuel injected engines seem to get a bit better, if you stay under 65mph .

yes that diesel does have its advantages.
I guess we gassers make up a bit in lower maintenace costs. Then again your diesel will probably do more overall miles. Oh well, either way you gotta be happy to have what you have

mileage calcs

I like it cold inside in warm weather, so I run all the air I can and when parked obviously get no mileage per gallon....the dog needs air, too.

I have run test hiway mileage and with no accessories running I seem to get close to double figures but under my normal running of the back roads and genset all together 7 seems to be the norm...jem

Mileage Update - Motorhome Miles Per Gallon

I only plan one more trip prior to the Texas heat making weekend trips unbearable.

I hope to add some ignition upgrades along with the new dash -
