I reviewing this with my mechanic he said I should be getting around 7 to 8, but I may only keep the rig for this year and then trade up. Don't know if I want to put a few hundred bucks into a carb for the under 1000 miles or so I will travel this summer. Given the age of yours and depending on how much travel you will do, how long you will keep it. After the tune up do you want to drop $$$$ to get a couple more miles per gallon?

I have a 1987 ford F350 460 hp 27 ft Honey and I was getting about 5mpg before I had the carb rebuilt, I am now getting 7.5 . The cost to rebuild the carb was $250 we only traveled 1200 miles this year so if I do my math correctly, I have paid for the rebuild. We are happier, though we would like to get 11mpg hahaha.
Do you pull a car? I am trying to find out if my hitch will allow me to do this. I have a 2" ball at rated 5000lbs on it but I found a note in the old manual Max hitch weight not to exceed 200 lbs / 2000 lbs towing capacity. What is a Car on a Dolly calculate out to?
Thanks

I have a 1988 Minnie Winnie on a Ford 350 chassis, 460 with a Banks Exhaust and 78000 miles on it. Had a complete tune-up and I get 8.8 mpg. I have read that if you put nitrogen in the tires you will pick up about 2 to 2.5 mpg. Will find out this summer as we are taking the "doghouse" to the east coast and back. Have a cruise control and plan on 55-60 mph whenever possible.

And if you put helium in the tires you might be able to pick up the coach.

Really!

Actually, yes. I was told this by the person who mounted my 6 new tires as well as reading the same from several RV'ers on other forums. Nitrogen is lighter than air and with 6 tires there is a difference in total weight. The down side is the tires ride rough when cold.

I would think this as suspect if I had only heard it from the tire guy, after all, he wants to make more money, never mind that I gave him almost 1400.00 for the 6 tires, but after reading it on other forums, maybe there is something to it or those people were all, shall I say, mistaken? I will find out in April

My father used to tell me that "Paper doesn't refuse ink" after I claimed to have read something that might not be true. In other words, just because something is written doesn't make it correct. In this era, "computer screens don't refuse electrons" might also be true. In my opinion, a 2 MPG improvement from nitrogen in your tires is absolute nonsense. Don't forget that your tires are already filled with approximately 70% nitrogen since this amount is in the air we breath.

There is a mileage benefit to using nitrogen; being inert this gas does not expand nor contract and nitrogen molecules are bigger than 'air' molecules so a nitrogen filled tire will stay at a much more consistent pressure than an air filled tire as far as leakage is concerned.

As in buying a diesel, one will never get back the cost of filling with nitrogen but if you need to be precise, go for it.

Information in this thread is why us "newbies" come here, ask questions and share what we have been told in order to find out "what is and what is not". I will admit that I am still green behind the ears when it comes to RVing. We have only put 600 miles on our "Doghouse" since we got it in May. Will be putting about 7000 miles on it starting in April. I do appreciate all the inputs and opinions. I have gleened lots of knowledge I did not have before now that will be a tremendous help on our upcoming trip, especially the information regarding using propane for the fridge while traveling. Happy Holidays to all.

I just made the trip from Chicago to Lake Havasu City in a 25' Chevy 454 P chassis. I pulled a 16' cargo trailer with a KZ1000 police bike and the usual cache of tools.

2385 miles
372.4 gals of gas
6.4 mpg
$1158.62 fuel costs

According to the GPS, my avg speed was 58 mph. I had the cruise control set most of the way just a fuzz over 60 and tried like heck to not open the 4 barrels on the Q-jet if I could help it.
