FreeAmerican replied to No F-bdy Bs's topic in 2015-2019 Chevy Silverado & GMC Sierra HDAgree, didn't GM put the Allison behind the 8.1?
In the EU there are grades of diesel. Its a shame the diesel we get here isn't any better. But, better diesel exists. Here I find it at stations that usually sell ethanol free gas, race gas, and some Southern States and tractor stores. My local ethanol free shop sell 47 cetane and I can tell the difference, esp in mpg.
I noticed after one of the ECU upgrades that my lower speed (esp 45mph) shift points changed. Originally I would have to speed up to about 50, let the transmission shift up, let off and drift down to 45. Now, about 45 or right at it, it up shifts. This helped my around town mpg a lot. I've noticed the lack of freewheeling too. On my 15 GMC 1500 you could turn it off by holding the tow button for 5 seconds or so. Helped the MPG on the 1500 as well. I have not found a way to turn it off on my 2500.
I agree with Cowpie on this. I was talked into the 1500 will do it. And then traded up to a 2500. I'm pulling a 32 foot, 7500 lb travel trailer and we tow it a good bit from end of march to Oct / Nov. And we venture out on longer trips a couple of times a year too. If you are towing 7000 lb + and or towing a lot, I would really suggest moving to a 2500. It made a huge difference as Cowpie pointed out. Because it is a much more capable platform for towing, when you get where you are going, you will not be as worn out, the entire towing experience is so much more pleasant. You still know something is hooked to your truck, but barely. To those who dislike the looks of the GM tow mirrors, they are not for looks. Honestly some of the best towing mirrors I have used. A lot of mirror surface area, the bottom wide angle mirror is in just the right spot. So if your tow is on the lighter side (say 5000lb or so) or shorter (length, surface area, other factors impact too), or you only tow local or just 1 or two trips a year, then a 1500 would do the trick. My 1500 was a 5.2 /3.42 and did a great job starting and even stopping my trailer, it was all those other factors that a max tow is not going to fix that pushed me to a 2500.
I got mine in June, z71 4x4 crew. Bought it to pull our camper, so reliability was a concern for us and I was a little worried at first. I had a CEL for the emissions that kept coming back. I did have some frustration but it was more with my dealer and their lack of knowledge on the new engine. But it turned out to be a pinched wiring harness that broke through the wire's insulation. They replaced the harness and that was it. I did get ECU and seat belt recall done. The ecu did seem to help drive ability and my commute millage went up a little. But no other problems and I am very happy with my truck.
Not sure where you get your number, but my 6.5 bed 2500 is 2100 lb heavier than my 6.5 bed 1500. I do agree the heavier frame, springs, axles and esp the brakes all add up to the better experience. As does the heavier transmission. But physics can not be denied, the heavier truck will have any easier time fighting a trailer.
I can give you some decent first hand knowledge. My current camper is a 31 foot pull behind, 6000 lb dry weight, 7500 loaded. 650 ish hitch weight. My first truck was a 15 GMC double cab, 5.3 flex fuel, 6.5 ft bed, Z71 (locking rear, 4x4, 3.42 gears, max tow 9400lb) I used an Equalizer hitch and a tekonsha p3, probably the best add on brake controller I have ever used. I loved that truck for day to day use. It would also start and stop the camp fine. The 5.3 is an amazing motor. Yes the 6.2 is a beast, but I honestly could not justify the extra buy in cost. It just didn't seem like smart money. I got good mpg for a 4x4 truck. Comfortable. But... We camp almost every other weekend from sometime in April until sometime in November. Various types of roads. The GMC did ok on two lane roads, rolling 55 mph. Power was no problem, going up hills was no problem. On the interstate, power was never a problem. Having to stop more often due to the 26 gal gas tank was a pain. But the 31 ft trailer pushed the truck around in wind and on the interstate. A LOT! We go to the outer banks and Myrtle Beach as well. On 95 south a semi passed us at 90 and cut us off to make an exit at the last min. It came so close to sending us into a flip from the sway. Calm hands and quick thinking to hit the manual override on the brake controller was what saved us. When I got home I bought a bigger truck, 3/4 ton Chevy Duramax. I went looking for a 3/4 ton gas but ended up with the diesel because we want to make some further out trips and even now we spend a good deal of time in the blue ridge and appalachian mountains. The reason to go 3/4 ton has nothing to do with power, the 1/2 5.3 has plenty of power, the 5.3 with the max tow (3.73 gears) will power it wonderfully. But you have 31 feet of sail behind you in a 5500 lb truck. You can do it, but you will have to pay attention to wind, traffic, road conditions and as always slow down. My 17 3/4 Duramax on the other hand, when we get where I am going, I am not as worn out, its a much more enjoyable drive. You don't get pushed around on the interstate, it is really a night and day difference. And has nothing to do with power. I will tell you I got regularly 20 mpg back and forth to work in the 5.3, but towing was at best 10, and a number of times in single digits in the mountains. Diesel, 15 mpg is what I get towing most of the time. long and short, it really is worth it to go 3/4 ton, esp if you tow more than a couple of times in the summer. If you only do a couple of trips, then you can get by with the 1/2 ton.
There are a couple of things to consider, cargo capacity and length / mass of the towing vehicle. So the dry hitch weight is 650. Right off with a 1500 that leaves about 1200 or so capacity. Add in weight for bikes, coolers, people and you start inching towards your limit. Add more stuff to your camper, the hitch weight goes up as well. Most people end up adding about 1000 lb of stuff in their camper. Dishes, food, chairs and clothes. If you are dry camping then add 4-500 lb of water. Just be conscious and realistic about your load out. Then you can consider the ratio of trailer weight to the tow vehicle weight. a 7000lb trailer being pushed by the wind or passing semi's will win over a 5500 lb truck every time. And the shorter wheelbase the truck, the easier it is for the trailer push it in different directions. I started off in a 2015 GMC 1500, 5.3, 3.42 gears. I added sumo springs and Bilstein shocks, P3 brake controller and equalizer hitch. My camper was about 7200 lb loaded, 31 ft long. It would start and stop just fine. But wind, bad roads, semi's, really made some of the trips pretty scary. We had a close call with a semi that cut us off. Then I moved up to a 2500 hd Duramax. The difference is amazing. When I get where we are going I am not as worn out. The trip is much more enjoyable and safer. And only about 10% of that difference is due to the diesel. Diesel is awesome for the gas mileage and the power but the safety comes from the 2500 chassis. You can do it with the 1500. I would do max tow if you do. If I were daily driving the truck and only tow about 3 times a year, 1500 would be a no brainer. We camp prob 12-14 times a season with at least two as longer trips. If your camper were a little heavier or a little longer I would vote solid to the 2500 side. But you are in an area on both where I think you can do a 1500 better than what I did. But.... a 2500 will always tow easier.
