It was just a matter of time I figured. The manufactures have sold millions of diesel pickups & now the gas companies get to cash in. I hate to say it but I'm not one bit surprised. That is why I never bought into the diesel craze. As a retired mechanic the cost to own a diesel doesn't pay unless you tow heavy all the time or run 50,000 miles/year min. First off the option cost is about $7000 that is 2000 gallons of gas @ $3.50/gal. Then filters that are twice to three times gas engines & 2.5 gallons of oil every 5000 miles.
The craziest thing I see are 90% of these diesels only haul kids, & products from WalMart. Pull a TT to the Lake 20 miles away from home. So if I was the gas companies watching this I would do what they are doing.
I tow a 9000# TT. Every time I sat down with paper & pencil there was NO WAY a diesel was cheaper than gas. Unless I was going to use it as I stated earlier.
Just my two cents. Sorry don't feel your pain, just buck up & pay now is all you can do. I see a lot of used diesels for sale on the lots that aren't moving these days.
