For what it's worth, we have averaged about 7.2 mpg's with our 42 ft. tag-axle coach at 40,039 lbs with almost 70,000 miles on the odometer. A tag axle does weigh more but it also offers more stability and a larger cargo carrying capacity.

Since you will be full timing, you will be carrying more than a part-time RV family. Your whole life will be in that coach so go as big as you can afford and with the most slide-outs. Also, a tag will give you an extra set of tires of you need to rotate to the front.

Once, we received a bad alignment (about 5 yrs. ago) and I didn't notice it until about 2,000 miles later. The inside of both front tires were wearing faster than the rest of the tire. So, I got an excellent alignment at TAFA in Nashville and rotated the tag tires to the front to have a fresh set with very little wear.

Last year, I bought a whole new set of new tires and went through the Michelin FMCA program for extra savings.

Good luck and let us know what you find.

Thanks for the info.
let me ask you this question?
You got 7.2 MPG with the tag do you think you would get around the same with 1 axle? 20% worse......?

We are currently traveling in the motorhome. I rechecked the Aladdin computer and my average is 7.8 over 68,700 miles. I have also every receipt for every tank of fuel with my miles written down (also aqua-hot usage) so one day I will figure it manually.

I honestly don't think the extra axle will reduce the fuel mileage much. The greatest advantage is the extra cargo carrying capacity and stability that it gives you. On a 42 ft. motorhome, it will take up some storage space.

If you are looking at a 41 ft. motorhome without a tag axle, check the cargo carrying capacity. You might be limited to just a few thousand pounds, whereas, we have at least 8,000 lbs. of wiggle room and can tow 10,000 lbs.

Good Luck.

Depending on how lead footed you are, expect between 7-8 mpg. A 45 ft will get from 6-7, and a 40 will average 8-9. These are typical mpgs, and your mileage may vary, but not by much. Additionally where you travel, such as mountainous or flat, and wind vs no wind will have huge effects on your mpg.

These numbers are dead-on....so a big X2

Thank you,
this is the info I was looking for

We got 9.7 on our last trip after just 3000 miles. We are 42' no tag. Weighing on the scale at 28,000 lbs of the allowable weight 32,400. Pulling our toad of 3900 lbs. 360 ISB.

In the real world I agree on the 6.5 to 10 mpg, all depending on vehicle, your foot, winds, weight, tires on ground.
But if you want really great mileage to brag about, use 8 one way and 7 the return trip for 15 mpg over all, you might be surprised how many must figure it that way from the stories I get at the fill up pump. Have mentioned before that my standard response is, "You best get it fixed, everyone else claims 19-23 mpg on your size rig" He thinks I am as stupid as he looks, we both smile.
You just gotta have some fun sometimes.

From the LA area to central FL in a 2008 Dynasty 45ft tag, 500HP towing a 24ft Featherlite trailer I averaged 8.5 mostly on I-10 at 65mph. My 97 with a 325 Cummins got about the same.

Thank you

When I was first buying my TV and asked about mileage, the salesperson gave the most accurate response... "If you have to ask you can't afford it."

Agree with most here, plan 8 MPG if you get more great buy an extra piece of pie at dinner, if less skip the pie.

I love pie, I just want to make sure I can afford it after paying to get to the restaurant

I have to ask the question: How much do you think you REALLY save if you get 10 mpg vs say 8..:h...less than the cost of a burger at MickeyD's....just sayin.....Dennis

Dennis from 10 to 8 is 20% more for a budget. I could probably live with that.
From 10 to 5 is 50% more budget and I can live with that if we give up food.

we could also stay home and get 100% better mpg :S
