Hi I am new to th forum and was wondering what you guys thought the best truck to get would be. I am buying a business and will be needing to tow a 14' or 16' cargo trailor with about 1000 to 1500lbs of cargo, so the total wieght should be around 4000lbs. Ill have to tow it about 500 miles a week. I dont live in the mountains or anything so dont have to worry about steep grades. Thanks in advance for your help.

If 4000 lbs is about the max you'll be towing I would stick with a 1500 series truck. A 2010 1500 with the 5.3L engine and 6 spd trans is rated to pull over 9000 lbs. The 1500 will also get better mileage and ride better when you're not towing. If you really want the 2500 truck, the 6.0L will be more than capable, and I don't believe the $9k upgrade for a diesel would be justifiable.

Thanks goforit I should have mentioned that I would be buying used 05 and up so I dont know if that makes a difference. I didnt know if the betterfuel aconomy of the duramax would make up for the difference in price. :D

The 5.3 will be your best bet. It will get close to 18mpg empty and won't do too bad towing. There is mis-information about diesel mileage and towing. They do not get the 13-20 mpg towing. A diesel can get great unloaded miles, but towing they go to pieces. I have owned 7 diesels and am speaking from experience. Just 2 days ago, my partner was pulling a dump trailer with john deere skid inside and averaged 5.7 mpg. After seeing the consumption on his display, we unhooked and hooked up my silverado. I ended up averaging 9.5mpg hand calculated. He drives a 2008 dually duramax.

Something to think about if looking for a used diesel..... My concern about buying a used diesel is all the folks that buy programmers and add them to their diesels. They seem as commonplace as canned beer nowadays. They're easy to install and remove and it's almost impossible to tell if a vehicle has had one on. This puts more strain on the engine, trans, and driveline than there were originally designed for. I don't know how much difference that makes but it's pretty much not a issue for gassers. Even chipped a gasser will only make 20-35 more HP than stock and only at very high rpms.

I just drove from the San Francisco Bay Area to Los Angeles towing a 6 x 12 box trailer weighing around five thousand pounds. On the flats going 65, I got 15.5 mpg, according to the DIC. I was pretty pleased because my Suburban with the 5.3 and 3.42 dif would only get 11.5 under the same circumstances. My guess is you'll do fine with the 6.0 but make sure you have the 3.73 dif and the six-speed transmission.

The 6.0 gasser should be fine. Since you are looking at a 2005, the good thing is that they have several years on the GMT-800 platform at that ponit, and all the little fixes were already done on the GMT-800 gasser platform at that point. The only issue that I know of from the GMT-800 Duramax are the cooling issues in the 04-05 years. I have a 2006 3/4ton gasser that has been great. The only downside of a 2500HD truck is gas milage. Towing is in the 8-11 mpg, with city being 12-14, and HWY in the 15-16+.

6.0L with the Banks Power Pack if you're thinking 3/4 ton. The Power Pack will bump your fuel economy a couple miles per gallon and since the truck is going to be used for a business it's a write off.

Trailer Life magazine did a comparison a few years ago between diesel and gas powered trucks used for towing. All factors considered, the diesel didn't begin to save money until the 100,000 mile mark, and that was when the diesel option was cheaper than it is now.

Take the 11.5 vs your 15.5. At a 4mpg difference over distance traveled, subtract the cost of fuel from diesel .40c and then figure the difference of cost of a used diesel compared to a used 5.3 ,then unloaded mileage, even if the same, still favors the 5.3 as gas is cheaper....see where I'm going?

Another thing....the DIC always reads more. I have never had a truck or car that is accurate.

wow thanks for all the responses! I realy am looking at the 2500 6.0 thanks to your imput. I found a 07 2500 single cab 6.0 WT with 34000 miles on it for 10500. ( old body style) I always overdue stuff so thats why I would feel more comfortable with a 3/4 ton. The current business owner drives a f250 powerstroke and my inlaws are in the same business and they drive a f250 and recomended I get a diesel. I gues they should have looked at a chevy :P

The only point I was making was that I got better gas mileage in the diesel than in the gas motor. I didn't buy the diesel for it's better mileage; I bought it because of the massive torque; the trans only downshifted once on my drive and that was going up a 6% grade. Also, diesel here is slightly cheaper than regular gas. I would never recommend someone buy a diesel for it's fuel economy because the upfront cost would take too long to get a payback; unless they drove 100,000 mile a year.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
