I do.

Excellent. This is what I currently do. I typically idle around the lot and park it and then let it sit for a few more minutes. Thank you! Brent

Very helpful. I appreciate that. What do you think about cool down time (sit at idle after use), especially the turbo motors?

Thank you. Good to know. We usually let it warm-up for 10 minutes but it looks like you're recommending 18-30 minutes. Brent

Thank you. When you say the truck should idle X minutes every first start up, are you saying after we change the oil or anytime the truck is started from a "cold start"?

Simp, is the age of the oil really that important (assuming it's not years old) or is it mainly the usage (miles & hours)?

Thank you Simp. I just don't have the time, nor the interest, to do most maintenance on the truck. I would much rather outsource it to a pro that can knock it out in 30 minutes and save me a headache and time. Without a doubt, it's worth it to me. It looks as though a new oil filter is...

Awesome, thank you. The shop I'll bring it to charges ~$100/hr so I should factor ~$50 in labor to the total cost? Labor: $50 Engine Oil (20qt, Napa): $57 Engine Oil Filter (Napa): $37 TOTAL FOR ENGINE OIL CHANGE + FILTER:$144. If I'm missing anything, please let me know. Thank you, Brent

Guys, I'd like my M939A2 engine oil and filter changed. After a light trail ride I inspected under the chasis and I noticed the oil filter was leaking from the top. Probably time for an oil change. I also don't know how old the oil is but I had a mechanic look at it almost 12 months ago and...

My M925A2 t-case gives us grief when trying to shift it. I'll try making sure the button on the t-case handle is working properly 1st then I'll check the linkage adjustment. If neither of those work, I'll try the interlock solenoid valve knock-out (page 1-35 on operator's manual).

Thanks MtnSnow. Let's assume there's a valve stem (insert) in position #1 and #2. Could I air up the tire manually on #2 position? I THINK all the tires have valve stems in them which is knocking the CTIS' functionality out.

Ok, Here's a photo of my front right wheel w/the protective cover off. I see two valves stems there ("1" and "2" as I indicated on the photo). Question: 1) Is valve stem "1" the stem in which I can remove the CTIS hose to manually air up the tire? 2) What is valve stem "2" for? I'm...

Ok, I went and purchased a gladhand tire inflator (gladhand + 50' hose + inflator end piece) from a local Mack truck center. I hope it fits on the 5 ton! I'll try adding air to the tires soon. I used to add air via gas stations....it takes forever and it's so uncomfortable being under that...

Great point Jbulach. I'll try the manual method you mentioned (adding air via valve stem on the wheel valve). Thanks! Brent

Thank you everyone for your input. I have a front tire that I'd like to put air in but my CTIS is non-functional and the manual-fill air stem is deformed/damaged so I cannot manually add air from the "inside" of the tire. I think the CTIS isn't working due to valve stems in so I thought I could...

Will the CTIS system work for some tires but not for others on the truck? For example, if 5 tires have valve stems in them, preventing the CTIS from adding air, but one tire doesn't have a valve stem, will the CTIS work for that one tire? Or will the system fault out and not do anything...

No troop seats. Just empty cargo bed. Thanks! Brent

I found this thread, but it doesn't indicate if it's for an M939 or M939A2 and it does not provide dropside height either. http://www.steelsoldiers.com/showthread.php?89943-Inside-Bed-Dimensions&highlight=bed+dimensions

Guys, I haven't been able to find this information in the manual or via search. Does anyone have official measurements (inside dimensions for the bed)? Normally I'd drive to the lot where my truck is and take measurements, but I'm in my work clothes. Anyone know where to find these details...

Yes, the CTIS has 5 flashing lights. It never functioned properly and my suspicion was that there were valves in all the tires. Are you saying that there is probably an air valve in that hissing tire and that's from the CTIS system trying to push air into the tire but it cannot due to the air...
