We are heavy at 55,500 lbs. Generally, we cruise along between 60-65 mph (we always have our tow car attached). In California, the speed limit is 55 mph when towing, so that's what I do.

I would say we are averaging about 6.5-6.8 mpg overall (currently we have 51,000 miles).

Safe travels,
MM.

About the only thing, I'm convinced of here, is that it doesn't cost all that much to tow and figuring maybe just 1/2 - 1 mpg. extra in a four down setup.

My 93 30ft p30 with a tbi 454 chugs right along and achieves 8mpg at 70-75mph. Going slower doesnt seem to help much. I wont go anywhere without adding lucas upper cylinder lubricant to the fuel. I honestly get an extra 1/2 mpg since i started doing that. I also removed the cat. I previously couldnt get more than 7.5 mpg.

I can't even believe that anyone would drive any behemoth that fast, let alone an older gasser.
Besides every thing else, most of these tires, have a max rating of 75mph and having a steer tire blowout, at that speed, can't be any fun, at all.
Also, if your speed has no effect on MPG, then there's some people at MIT, that would be very interested in talking with you, about how you have managed to violate the laws of Physics.

Haha maybe i should have went to college after all. Its definitely a measureable amount better if i go slower (not buy much at all), its just not worth it to me if i can legally go with the flow of traffic. Hey a passenger car doing 80 can blow out a front tire too. Everything is a risk to some degree. I keep my rig very well maintained and look it over before every trip and at every stop. I understand what your saying though. I go slow when its necessary.

The lucas works! Lol it sounds like a hoax but it helps. I also like that it adds some lubricity to the fuel. I need this old chevy big block to last a while!

I get between 5 and 6 (OK, 5.5) no matter how fast I drive. Now, I have to admit that I have never driven 55 for any length of time so mostly 62 to 72. I would rather poke my eyes out than poke along at 55! Even if it were the difference between 5 at 70 and 7 at 55 MPG I would not never choose 55. Let's do the math. An extra 2 MPG over the average 10,000 miles driven by RVer per year. That means you get to drive an additional 2 miles for every gallon of gas used. 10,000 miles divided by 7 equals 1428.6 gallons of gas. 10,000 miles divided by 5 equals 2000 gallons of gas. That's a 571 gallon savings over the course of a year. Maybe $2000/year savings but it took you an extra 666 hours to get there. It's about balance. $2000 is a lot of money but time has value as well. I like to "be there" more than I like "getting there".\
YMMV!


What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

^^^^^^Agree 100% west of the Mississippi I'm usually at 75mph going with the flow of traffic. Mileage is not really a concern .

Have put 149,850 miles on my rig since 10/16 heading to Delaware to purchase 10 tire for the rig, 4 tires for the trailer and 4 tires for the explorer. So at 7 mpg I have purchased 21,407 gallons of fuel. Yep it's an expensive lifestyle but I enjoy it being able to go when and where I want.
