I like to think I can improve my mileage but it doesn't seem to help much - especially since I drive the hills. I seem to get slightly over 5 mpg whether I drive 58 or 70. I knew it was going to be expensive to operate but we are full timers right now. I figure if I was in a house then I'd be spending money mowing the lawn or fixing the roof or whatever. I'd be thrilled to get 7 mpg but I don't see that happening with my setup.

I care, don't get me wrong.
If I look at this in mathematical way ( my wife just hates it when I say that) If I were to say, gain a half a mile from 6 to 6.5 at 140 gallons ( 80% of tankage) I gain 70 miles on the tank it gives me less than 11 gallonsof fuel extra @2.75 per gal that comes out to $29.15. Yes it is a savings but then on a long trip I am also 70 miles further down the road. If I am on a 3 day trip to destination I will be 1 day ahead of the game and out the $58.30 which is what 1 1/4 campsite?
Trust me I look as you do on what a trip will take in expenses. My first trip to RITV was 2600 miles, 433 gals @ 3.25, $1,407.25 in fuel. That's a big swallow. $500.00 for entry fee, $300.00 for crap at the vendors, $500.00 misc stuff on the road and around Perry, A whopping $2,700 bucks for a short trip to see people and things I might not even like........
In any case we should always try to save our selves some bucks in anyway we can but remember theONLY thing that we can not buy is time. Time in some way is the most precious thing there is to us.
To save dollars we all could have purchased a 1976 Winnebago Chieftain and bought Chevy big blocks by the trailer full to keep up and you would have had the same mileage that you have in your BEEEEEutyyyyfull BB LOL!!!!!
See Ya!!!

I interpret what Al is saying is that he can afford "it" and so he doesn't worry about mpg. He has a point. Certainly, worry isn't going to get a fellow any better fuel economy. That being said there are folks who have to consider each and ever trip and the costs involved, it's a fact of life. How many of us are on what side of this bell curve I have no idea but I would guess there are darned few who wouldn't appreciate an improvement of one or even a half a mpg. I know I would. So this discussion seems relevant to me.
While shopping for bus I ask a PO what the fuel usage was. His comment was if you have to ask you can't afford it. You know I didn't buy that bus, and I am not too certain that comment wasn't the biggest reason.
I am only making an assumption of what Al meant by his comments. And I take no offense either. It is what it is for each of us. I am not without but I must admit that filling the tank causes me to wince. Some would wince regardless of their financial circumstances. Some of the wealthiest people I know would complain the loudest. And on the other hand I wonder some times how I will finance this as time goes on. For the time being I am with Al enjoy it because time is what is most fleeting. I am grateful that I can "play" and pay to play but I also do not take a bit of this as a given.
Not sure that I added a thing to this conversation but I had to comment.
