I often hear a lot of talk about cost of diesels and the need to keep them for extended periods to pay for them.
Well, it's kind of a half truth IMO.
A diesel does demand a premium over a gasser at purchase. No arguement there. But, it also demands a premium over a gasser when you sell it. This added in with the fuel savings during ownership, make the price difference pretty small. I've often come out ahead of the game buying/owning/selling a diesel over what the same truck as a gasser would have been.
People often mention the increased service costs.
True, there is more oil in a diesels crankcase. The difference is about 20 bucks per oil change.
A diesel also doesn't require spark plugs. Although with 100,000 mile gasser plugs these days it's not so much a factor.
Gas and diesel both require fuel and oil filter changes, not much difference there. Maybe 20 bucks at each change in the diffence at most.
People cite diesels as "noisy". Modern diesels are pretty quiet. Not as quiet as a gasser in day to day driving, but not far off. The last Duramax I drove was so quiet, I had to actually listen for the diesel noise in the cab. Having a normal conversation standing by the hood was no problem. The newest Fords are supposed to be even quieter than the 'Max. And there's the better MPG to help make you feel better about the very light "clatter" if you do hear it. I'm maybe a bit of a throwback, I like my diesel clatter a bit louder. My 98 IDI 6.5 TD makes a wonderous cacophony of sound! I bought a diesel dad-gum-it! I want it to sound like a diesel!
Finding diesel fuel is often cited as a PITA. I've never had a problem finding diesel. On the highway or in town. It may have been an issue 20-30 years ago when most diesels were just over the road trucks, but the increase in light duty truck diesels and diesel power cars (vw being the big one in NA) have made diesel pumps common.
Only problem I've ever had with diesel is getting that bloody 35 foot trailer to fit in a tiny gas station parking lot. But that's the same with a gasser.
At the end of the dayit's a personal decision based on your specific use.
You can tow with a gasser, no question about it. If I were planing only shorter hauls and light loads, it might make more sense.
But a diesel makes towing heavier loads longer distances a much more relaxed and enjoyable affair. Better MPG is just gravy.
I also find the extra weight in a diesel truck a bonus when controlling the trailer. Diesels are a fair bit heavier than a gasser truck. I find it helps when 8000 lbs are trying to "push it around". Of course, that extra weight can also cut into the trucks payload and there's an MPG penalty for extra weight. This is usually countered by the diesels ecomony anyways.
I'm slanted towards diesels for towing, but a gasser can be a fine choice also. I wouldn't turn my nose up at a good deal on a gasser, but it would be for uses other than towing for me. You just have to get the right gasser for your particular towing job.
Your greenbacks, your call.....
