Joined Jul 24, 2005 Messages 1,039 Location Chester County, PA Tractor Kubota BX24, Case 580 Super L There are two trucks that I'm looking at, as I consider whether or not to buy a truck at all, and one has the 6.0 and the other has the 8.1L. Otherwise, the trucks are pretty much the same, one's a 2004 and the other's a 2005, both four doors with an 8' bed, and around the same mileage. The 8.1 does not have the Allison transmission. Both are 2500HDs. The prices are close enough to be negligible. The 6.0s are much more common, and I like to have things that are common, because of additional resources in knowledge, better parts availability, etc. So, all other things being equal, which would you buy? This truck would be my daily driver. It would not see any really heavy work, just towing my subcompact TLB (BX24) from time to time, perhaps towing a 3400 pound car on an appropriately sized trailer, and perhaps the occasional rental of a dump trailer for getting sand. I have heard people mention before that the 6.0 might be a bit too underpowered for a full-length truck like this, but most of that comes from the truck forums where people seem to be more about having their trucks than using their trucks, so I don't really think the opinions are impartial. This is also why I chose to ask here instead of there, since most people seem to select their trucks as tools that they need, not trophies. :thumbsup: Thanks for any feedback.

I have never owned an 8.1, but I have heard that there are issues with them on rare occasions. A friend had one and beat it senseless and never had an issue with it, so who knows. Either one is gonna drink some gas though. Feb 22, 2011 / 6.0L vs. 8.1L in a Chevy truck #3

The 6.0l is certainly adequate for your needs and much cheaper to maintain and run. Do they both have the same rear axle ratio? Feb 22, 2011 / 6.0L vs. 8.1L in a Chevy truck #4

I didn't think to factor that in. Given a choice between two different ratios, I'd probably go with the higher gearing since the truck will be used mostly as a commuter. Thanks y'all.

Doesnt really seem to matter if I am pulling the horses or the car trailer. The 6.0 does everything I need it to. For what you describe I think you will be happy with the 6.0.

I have not had a chance to do much towing with it but the truck has power that's for sure. A freind of mine is a masonry contractor with a 3500HD dually. He has the 8.1 with Allison. It is a pulling machine. I have seen him pull loaded trailers out of the mud that a newer PowerStroke couldnt budge. He has 4.10 gears. 8-9 mpg See this for link to my truck http://www.tractorbynet.com/forums/trailers-transportation/197020-2005-chevy-2500hd-crew-cab.htmlAttachments

Joined Jan 18, 2007 Messages 16,331 Location Daleville, IN Tractor Jinma 254/284 Ford 861 Powermaster at work I would go with the 6.0L for your needs. I have had a couple 8.1L's in boats and while they are a power house they uses oil and gas. As pulling a load there is no way any gas engine is going to out pull a modern diesel of any brand. It comes down to getting the power to pull the load. In a stuck situation a diesel has so much low end torque it can be a hindrance. I have 2 diesel trucks and have owned 4 and over a dozen gas trucks and I can tell you for a fact that my current gas truck is my preference for snow and mud situations versus my 2 diesels. In 04/05 the 6.0 was only available with 4.10 gears I believe. The 8.1L could be had with 4.10's or 3.73's Chris Feb 22, 2011 / 6.0L vs. 8.1L in a Chevy truck #10 BBaucom

Joined Feb 10, 2005 Messages 360 Location Boiling Springs, SC Tractor MF 2823 Of the 2 engines you're looking at, I'd take the 6.0 for the marginally better fuel economy. Are you sure a 3/4 ton is really the best option for your uses? I'd think a late model half ton, say 05+ with a 5.0L+ V8 and proper gears would do everything you need to do at a much lower operating cost and make a better daily driver than a 3/4 ton. Aside from perhaps the occasional rental of a dump trailer for getting sand, I don't see anything you're planning to tow that should weigh much over 6K, if that. For the difference in operating costs I'm sure you could have your sand delivered and still come out $$$ ahead, or you'd have no problem with a dump trailer with a loaded wt. of 9.5-10K. A GM 5.3 V8 w/ 3.73 gears, Ford 5.4 V8 w/ 3.73 gears, Ram 5.7 V8 w/ 3.92 gears, Titan w/ 5.6 V8 & towing package, or Tundra w/ 5.7 V8 would all be more than capable of doing what you've mentioned.RayCo said: So, all other things being equal, which would you buy?

Click to expand...Believe me, I have been struggling with this for a year or more, as I've pondered getting rid of my Tahoe. A 1/2 ton truck would be fine for what I need, as far as the towing goes. But, I figure if I'm going to get a truck, I should have an 8' bed, since the bed is the main purpose behind a pickup truck. But, since the vehicle will also serve to tote around a family of four, a back seat is necessary. I would be fine with an extended cab, but my 4.5 year old daughter has told me repeatedly that she'd be sad if she could no longer put her window down. So, that means I must get a four door truck (or wait until I can afford one of the newer trucks with the windows that go down in the extended cabs). Unfortunately, there is no such thing as a four door 1/2 ton with an 8' bed. I fear that if I compromise, I'll find myself shopping for a replacement truck much sooner than I'd want. Part of my problem is that I am suffering from what I call Tahoe Syndrome. I could/should have gotten a Suburban when I got it, since it's the same thing but with more room. I've cursed the cargo area of the Tahoe many times, and I don't want to wind up doing the same thing with the bed of a truck. If I get an 8' bed, and it's not long enough in some situation, at least it won't be because I got the wrong thing. I've also toyed with getting a regular cab truck and some economical 4 door sedan, but that opens up a whole new list of issues. What I'll probably wind up doing is nothing.

I've towed 12-13,000 with mine (JD 720D w/500# of wts., plus second trailer w/4 bottom JD mounted plow). We have a pretty fair hill outside of town that's over 1/2 mile long, I could gain speed all the way up if I wanted! Of course, the gas gauge went down all the way too. Don't plan on very good gas mileage though, maybe in the area of 15-16 at best. I went down to a 2006, 1500 w/5.3 as I don't tow more than 7,00 now, much better gas mileage. as for the bed length, I'd rather have the 6-1/2' bed (NLA on a crew cab), but I'll live with it. If I'm going to haul more than tools, I just hook onto a trailer! ~~ grnspot110Attachments

Joined Jan 18, 2007 Messages 16,331 Location Daleville, IN Tractor Jinma 254/284 Ford 861 Powermaster at work Biggest issues with GM Crew Cab Trucks is the back seat is a little on the small side. Even compared to the F-150 my 05 3500 was a little tight. Its the biggest complaint I hear about the GM crew cabs, especially from guys who had Fords or Dodges in the past. Remember, them kids get big quick. My neighbors kids both were under 4' in 07 when he got his 3500 Dmax and now both are nearly 6' and cramped. Chris Feb 23, 2011 / 6.0L vs. 8.1L in a Chevy truck #14

Joined Oct 25, 2008 Messages 13,640 Location West central Illinois Tractor JD 2025R I have had Quad Cab Dodge trucks since 1998. I recently sold my Dodge truck and bought a Dodge Challenger, and a 2002 GMC regular cab 8' bed 4x4 truck. This happened last Sept. Since then I have missed the 4 doors on about 2 occasions. In both cases three of us were in the cab, which is a little tight, but it was for very short trips. I have two kids plus the wife, so the only time it would be a serious issue would be during a winter storm, all of us can't ride in the current truck, but could if we had a four door. What I'm trying to say, you might not miss having a 4 door truck as much as you think. Most of the time we all drive somewhere, we take the wifes car. So a truck and another car aren't that bad of a option. Feb 23, 2011 / 6.0L vs. 8.1L in a Chevy truck #15 TTRR

Joined Dec 21, 2010 Messages 296 Location Central Texas Tractor Kubota L235 For the options you present, I'd go the 6.0 route. I've found that it's always better to get a little more truck than you think you need which it appears you are doing. I have a 2004 2500HD w/ the 8.1. I researched the 6.0 & 8.1 and found there is not that much difference in fuel consumption, I get between 10 and 14 mpg. I got the 8.1 primarily so I could get the allison. I have had to replace the camshaft at 140,000 miles. Otherwise it's been pretty free of maintenance problems and has performed well at sea level and 11,000 feet with a heavy trailer. I tow about 70% with 6,000 to 10,000#. Feb 23, 2011 / 6.0L vs. 8.1L in a Chevy truck #16 Diamondpilot

With all the EPA stuff, you have to swap in an identical motor. He was lucky to find a replacement in three months and the auto salvage had him by the short hairs. The 6.0 will do the job ,get better mileage, and be much more easily replaced in the off-chance of disaster. Feb 23, 2011 / 6.0L vs. 8.1L in a Chevy truck #18

That's probably the baddest gas engine ever built. Back in ~'06 one of my subs had one on my jobsite. Got to take it for a spin a few times. That thing would have pulled the shorts off my 7.3L ford Powerstroke. Liked it so much I offered to buy it from him, but he wasn't selling. :laughing:- 1
