That is about double what the gassers are claiming. With gas at $4 /gal (maybe a tad less) and diesel at a tad less than $5 a gal. That is false economy to think you are saving money. You get about a 20% cost saving on the gas, but almost a 50% loss in mileage

Realizing of course the higher initial price of the diesel and more cost in maintenance. But a large increase in pulling capability.

If you want to compare, compare apples to apples.

Cost of def?
Increased cost of maintenance on a diesel for oil changes? Etc…?
Initial cost of Diesel engine is $10k minimum over a gas burner.

I don’t know all the answers, and each person must weigh their options. Just make sure you compare all the details.

It seems the diesels hold their values, but even repairing injectors and such is extremely expensive.
