Default Diesel trucks

I am looking at diesel trucks which I know ZERO about them. Truck usage- daily driver, towing commercial mowers around town. The big concern is towing a 21ft Robalo from Nashville to Orange Beach several time throughout the yr. I've been using my Tahoe and Silverado which are 5.3s. There seems to be strain on the engines on the interstate. Max speed is around 65mph. Should I go to a diesel or a bigger gasser. One dealer tried to steer me to the Ram Ecodiesel? What's the good and bad ?I've read mixed reviews as far as cost vs performance. Any real world insight is appreciated. Robalo dry weight is 3500 fuel capacity 70 gal. Trailer weight aprox 2000lbs. Thanks in advance.

As much as I'm a diesel fan, I don't think that you need one for a load that small. I'd go bigger gasser personally.

You are going to get a lot of opinions, from those that say a 1/2 ton will tow 12k, to you need a diesel dually. The new diesels emissions can be problematic, keys to longer life running them at temp and limiting idling. I have owned a 3/4 ton or one ton diesels for the last twenty years since I love torque and the last two boat and trailer combos are 14k and want a diesel to do it. It sounds like for your purposes, many different trucks could perform what you need. One of the few pieces of advice I give is just make sure the truck is set up with the tow package and higher gear ratio to make the towing easier.

how much weight is the commercial mowers? For daily around town towing i'd recommend a 3/4 ton gasser. Probably will get similar fuel mileage towing to what your 5.3 gets. Generally stay away from the ecodiesel. A half ton other than the 5.3 would handle your loads just fine, but a 3/4 ton will last longer, as i'm assuming you are a landscape contractor and spend more time hooked to a trailer than not.

Bigger gasser will be fine. 5.3 gas is an anemic point of comparison. If you want to stay stupid simple, a 5.7 Toyota would also be a solid choice.

I'm looking at the 3.0L Duramax. A contractor friend of mine told me his is getting 28-30MPG avg. He also said his crew loaded his dump trailer with old shingles and it pulled like a champ. He pulls trailers all the time and swears by it. It's no 3/4T, but seems to be a solid platform.

I’ve been daily driving DuraMax trucks since 2006. The newer rigs, with DEF/DPF systems don’t really like a lot around-town driving, short trips. They need to get warmed-up and stay warm, otherwise soot collects faster in the DPF. Unless you’re going to have a daily 10-15 mile drive at minimum, I’d recommend a gasser for your application.

Probably 2k to 3k with the mowers 5.3 does fine. It's the long hauls with the boat that tax the 5.3 especially on hills. You are correct my truck has a trailer on it more than not.

I dont I was just making the point on interstate travel the 5.3 seems really taxed especially on inclines. I'd like to travel 65 mph with ease.

I just bought a 2020 GMC AT4 with the 3.0L diesel. I had a 2016 Suburban with the max trailering package before. The diesel gets amazing mileage and pulls my 24 ft Key West way better than than the 5.3L did. I just got back from a trip to the North Georgia mountains and averaged 24 mpg. I've put 1700 miles on it, and the DEF gauge has barely moved.

The power and gas mileage of this engine seems to be the best compromise if you can't justify the big 2500. I couldn't justify the HD truck for my everyday driving.

I towed my 23’ CC (7000lbs) from Kentucky, thru Nashville, to Perdido four times a year for a decade with a 5.7 tundra. Tow haul. 5th gear. Cruise set at 70 - 98% of the time. The other two percent was a downshift to 4th for a particularly steep section. 8mpg.

I now own a 2020 Powerstroke and it will tow the same boat at 80 in 10th gear and NEVER downshift unless I slow for traffic or something. Effortless. 14mpg. Extreme overkill. It brings a smile to my face every time I hear that turbo spool. Time will tell if I dare keep it out of warranty.

If your business/daily use of the truck kept you generally off interstates and involved a lot of stop and go short hops from site to site...gas all the way. A 3.5 EB will absolutely stomp all over the anemic 5.3s. Any of the 5.7’s to 6.2’s from the big three or Toyota with tow packages will too. A Ford 6.2 or 7.3 gasser in a 3/4 ton would be up another level from that and the diesels would be king of the hill.

Buy what you want and can afford. They all will be light years better than your current rig.

I've been driving my 2005 Chevy Duramax since new for 276,000 miles. I really like it but I often tow as much as 10,000 pounds with the truck carrying another 2,000 to 3,000 in the bed. My truck doesn't have DEF or DPF to deal with.
I use my 2009 2500 Suburban with the 6.0 to tow my boat which is 6,500 pounds on the trailer. I can maintain 65 mph up mountains with the AC on and as many as 7 people and gear in the Suburban. The 6.0 is more than up to the task for your use. I wouldn't want to deal with a new diesel with their complexity and emissions if I didn't absolutely have too. I think you would be much happier with a gas 2500 for your application.
I will need to replace my truck in a year or two. I'm still not convinced I will get a diesel again. I'm actually considering getting a gas truck and putting the savings toward a used class 8 road tractor to pull my flatbed equipment trailer.

You must not have the 342 gears. 342 Gears in the 5.3 should handle those loads fine.

Anything less than the 342 gears in the 5.3 isn't good at towing.

His loads were under 5,000 pounds. Gesh what the hell does he need?

I have towed with a 5.3 Yes they suck with to much weight. But damn 5,000 pounds and under is nothing for that engine.

I owned every diesel from the big 3 in the HD trucks over the last 22years. I’ve had my 7.3L for about 1.5 months now and tow with it all the time, well over what you’re towing. I wouldn’t take another of these modern diesels over this at any time. MPG isn’t great but gas is edging towards a $0.50/gal delta again and a $10K premium on an engine I wouldn’t keep a day past warranty makes a big financial point to me.
