What did you do with your GMT400 today...or yesterday....

[MrMarty51]

I got rid of all my steel wheels. Just gave them to the tire shop when I had new tires installed on my Alcoas.

Alcoas is mighty nice.

One of the aluminum wheels on my truck has a short crack from the rim inwards. It leaks but real slow. Takes a month for it to come down about ten PSI.
I know the stock steelies aint going to look so nice as the aluminum units but I kind of want to get the truck back to looking closer to stock, close out Your vision to the roofing racking.


And the boooolitt holes.
Chain busted pulling stumps. Left this line of little dents and dings in the paint.
I covered each one up with a bullet hole.

Now I’d like to find some real tiny bullet holes to place in the middle of the ones thats now on there.

Maybe I think I figured out why fuel mileage is below what I’m expecting.
Them mud flaps, them things are huge, blocking lots of wind, and, they ate dragging on the ground and streets.
Thats gotta be a big part of it I’m sure.

Okay, after that last post, I better suit up and go for a Harley ride.

@MrMarty51
I would tend to think your 4.10 gears are having impact on the hiway mpg. Did you get a lot better mpg before part of this build?

wide tires will also effect mileage. I swore up and down that after I went with the all terrain tires on my 95 I lost mileage though everyone I have talked to and seen the tires says otherwise. they are wider and have heavy tread, not so much that they sing. the main thing I noticed on them were the width. even though you can set another normal 265-75-16 tire next to them, these are more like a 265-85 or 95 size. not to mention they are heavy too!

Mileage before the new engine was a pretty steady 15.5 highway/city combined.
So its actually about 1 MPG off from what it was.
1 MPG does add up and it dont take long.

Tires on My truck are 285-75-16s
They too are quite wide and tall.
I had to adjust the torsion bars a long ways up to keep the tires frum dragging against the inner fenders when cornering and a rough area is encountered.
I’m wanting to get these tires down some more before encountering the price of a new set of tires that are not so tall and not so wide as these.
It was suggested that 235-85-16s would be a real nice fit.

That's what ai ran on the 94 dually.

I have them on the 94 srw now. But will go back to 265/75R16 if the situation ever arises

Installing the new reman hydro boost.
Another thread started on a little retainer clip.

Road Trip to Kingman to grab a 24’ trailer to help my buddy haul some stuff back down there next week. We linked up for fuel in Cedar City UT. Before he headed home for another load. He’s got some stuff here in the Salt Lake Valley I’ll take back down to him.





I grabbed the stuff from a mutual friend north of Ogden. About a 1000# of long steel and car stuff and brought it home until I leave again. Drove the 80 miles home with a fast moving storm closing in the whole way. Very strong cross winds coming over the high sound walls made for an unpredictable ride.

The winds that were already a problem really began to intensify as I got closer to home, clouds to the north of this picture were spinning in a large circle and the sky had turned an ugly grey-green (in Iowa and such, that means bad things for Dorothy and Toto).


Got home and initially covered the important stuff as it was sprinkling (40-50 mph sprinkles). But, as I started securing the tarps with ratchet straps vs. the whimsy bungee cords, the sky opened up and the now wind driven rain/sleet/snow was most unpleasant…

Love me a nice long hot shower!

Truck ran great. First real long pull for anything in a very long time. 16mpg coming out of Vegas up to Cedar City on I-15. Quite a few climbs on that route. IYKYK. Of course, no wind resistance on a 2500# flat bed vs a 5000# camper helps.
Glad I wasn’t pulling a toy hauler in those winds.
