    94' RD, 300 hp, 13 sp, 3.63 gears ......Today I got 6.4 mpg hauling drywall on my flatbed. I normally get 5.5 to 6.0 mpg. I tried a different driving style though after reading an article on fuel mileage. I am going to try it again on monday, and I will let you guys now how it worked out. Hey Warpman I saw you out and about the other day. Once in Plainfield. and then in Marengo one afternoon. That's a pretty straight looking R model you have. See ya around. Brad

    Well how about that! My main office is in Plainfiled, and we have an additional farm in Marengo. What color is your truck? Then I will be able to recognize you.

    We have a couple Mack CH's with a million miles on them. The one has only had rod and main bearings a few times. It uses about a gallon of oil between changes and still gets 5.5 - 6.0 mpgs. It runs decent (won't snap your neck), but it goes every day. I don't think you could ask for much more than that. Thanks, Brad

    hey storkmack,
    i noticed in your gallery pictures there is an '85 r-model and the caption says you are in a sod field. its ironic because i work at a sod fam, Central Sod Farms, and we have farms in Plainfield and Marengo. What farm were you hauling for?

    Lately I've been trying to put a deal together to get started on scrapping,but the new scrap buyer up here isn't open for business yet.

I fixed a couple of ongoing problems on the Harley,had a motor home given to me,gave it to Northern Nevada ABATE,built a storage shed and filled it with stuff I had stored in my shop,now I'm finishing an engine replacement I started a couple of years ago on the Chevy Citation my Dad left me when he passed away. I started on it a couple of years ago,things got busy so I tabled it;last winter I found a deal on a good engine,bought it and it sat in the shop on an engine stand until about a week ago. It's nearly ready to run now;I still have a little wiring and vacuum plumbing to figure out,an oil change,a carb rebuild,a cap-n-rotor and one CV boot to replace,and it should be ready to rock. :o Don't EVER let me work on another front wheel drive!

    You're busy as usual I see-i've been on vacation this week. didn't go anywhere,just hung around the house. By the way,my Norton 360 antivirus that came already downloaded on my pc was about to expire and cost $59.99 to renew for a year.I was talking to Old Bill,the diesel gypsy,on Skype the other day and he sent me a link for a free antivirus download called "Avast". He says it's better than Norton. He uses the pro versian himself,but said the free version was all I needed for my pc.I like that part-"free" :D

    :SMOKIE-LFT:
    Me too-free is good medicine,and I'm not out a cent if it doesn't do what I need done;my Norton expired some time ago so I was relying on a few free-downloads for different jobs. I've used Avast-it's pretty good. I also used "PC-cillin Housecalls" and a registry cleaner I can't remember the name of,they helped,but not enough.
    Apparently,this bug had been drifting around in my computer for a while;a couple or three months ago I started having some miscellaneous little troubles,first part of my desktop settings quit working and I couldn't change the desktop picture. As time went on,things just got weirder and weirder,the problems got more invasive,and finally one morning,my desktop picture came up bright red,with that "TOXIC" 3 half-circles emblem in bright yellow in the middle,and nothing would work. I couldn't even kill the pop-ups that were on the screen. "Control/alt/delete" just made more pop-ups that also wouldn't go away.
    When I had the shop blast my computer,they reloaded the operating system,with XP Pro,and a lifetime version of AVG;it works pretty well. Kind of a pain to work with though,because it stops just about everything you try to open,and you have to okay it before it'll load. AH,the high price of safety...
    My sister was always harping at me"You'd better be careful what you open,you'll end up with a computer virus!!" She hasn't missed a chance to remind me that if I had quit going to all those obscure websites looking for parts and car/truck/bike pictures,I wouldn't have this problem. Well,I guess it's MY turn now,because HER computer has a virus now,and it sounds like it could be a version of what mine had. Not so funny now,huh Sis?
    Well,better get to work.
