What is the Propel fuel? I have never heard of it.

The Cowdog just keeps getting driven and driven like a regular vehicle. Over 300 miles during thanksgiving and another 300 yesterday for family visiting. 5 adults traveling in comfort at or above open highway speeds. Running 75-80 for hours on end used to get me 16.5-17.5 mpg. I guess the new...

The pictured fore stock mount shouldn’t be a problem. However, since the Suburban floor is different than the truck floor. The butt stock mount might take some imagination.

I don’t know where the truck rifle mounts go. The m1009 rifle mounts will fit the suburban though I didn’t use them because the rear speakers are in the way. I kept the speakers.

Glad I’m not the only one overlooking it.

Life cones at you fast. I think that is a line for a commercial or something. But it sure is true. I went looking for this thread and was amazed it has been 3 months since I posted to it. I have more reasons to confirm that I am an idiot. When I built the truck I didn’t have a crack free...

I forgot to write about the brake upgrades yesterday. After my trip to the mountains I installed some performance front brake pads. Hawk Performance HPS to be exact. They are expensive: https://www.amazon.com/dp/B000CO6634?psc=1&ref=ppx_yo2ov_dt_b_product_details But, they work amazingly...

The Cowdog pulled the 6BT M715 we have been working on for Sermis the last decade or more out of my class last Friday. Then, Saturday I drove it to his place 90 miles away. This is the heaviest load I have ever had on my trailer and the Cowdog. His engine is about 600 pounds more than the 6.2...

He almost got me for the TCC switch and wiring harness but I wanted to do the test to see if it would even work. He gave me the part number in case I decided I wanted it later.

I did some more research about engine braking with the 4L80E. Then I read through my Compushift 90 page manual and found an option for locking the torque converter in any gear. That made me curious so I called them up. I bought their transmission control module 5 years ago mostly based on the...

You hit on the main reason I haven’t even search for exhaust brake information yet. Intuitively it seems turbo damage is a very real possibility. That is why Jake brakes are preferable in my opinion.

Keith, the 4L80E coast in over drive. If 1, 2 or 3 are manually selected it will bring the engine rpm up. But, with no throttle valve or exhaust brake. The diesel just revs but doesn’t really contribute to slowing my 7-8K pound truck on the steep grades. 1st selected would have the engine up to...

Thanks for watching. The Cowdog did do good and I still need to get 1300 miles home with it. But, after the first 90 miles it will all be a gentle decent of almost 5,000 feet.

Jennifer and I have spent the last week and a half driving the Cowdog around and over the mountains of Colorado. I never really appreciated what no engine braking with the 4L80E meant until this trip since I am a stupid flatlander type. I now need to move away from stock brakes and go race truck...

What do you want to know Chis? It is a Compushift without the bluetooth option since it is now 5 years old: https://www.hgmelectronics.com/transmission-controllers/

I have written a lot about injection pump timing in this thread with promises of a video of how to read the timing. I finally got around to making such a video:

I towed the M715 behind the Cowdog to the Rally last weekend. Here is part 1 and 2 of a video I made during the drive showing the Compushift display, boost gauge, EGT gauge and water/meth controller: I couldn’t get it in the video. But, my coolant temps would rise to 215°-217°. Then my...

I think they had a few bad batches. 3 of my trucks have 10 year old 60G’s in them and work perfect. I’m on my 3rd set now in 5 years with the Cowdog.

My son Colton is living his life 60 miles away with a job in a town 75 miles from there. We don’t get to see each other much and maybe talk every other week or so on the phone. Trying to keep him up to date on things I am doing is difficult. He suggested I just start doing videos of what I am...

Soapy water would probably work just fine. The stuff I have is called Big Blu micro leak detector for air conditioning. I was expecting at most a few small leaks. Not the massive things I had. I pulled the CUCV 6.2 intake that night after I took the video. Then installed a 3 piece 6.5 center...
