  Of course that would be false. You could have had one welded into your stock pan if you could find someone who did TIG welding.
- Front hitch/ winch mount build
  
  By HoosierZ · Posted 4 hours ago
  
  I was recently given a cheap winch for my trailer and I’m going to build a front receiver hitch so that I can use it on my truck also. It is a 13,500lb Sinoking winch with synthetic rope and wireless remote. It is mounted on a Badland hitch mount. The lower plastic was removed from my truck several years ago when I built a custom tube framed skid plate for it. The hitch will be tucked up close to the bumper and hopefully I can add a 2” square tube to the back of the skid plate to fit it into the hitch to hide the hitch when it’s not being used. More pictures to come.
- Measuring Transmission Temperature for Setting Fluid Level - 6L90

  Hi All, I am curious whether using the dashboard display for transmission fluid temperature is considered acceptable when setting the transmission fluid level after a pan drop, filter replacement, and fill. I have a 2021 gas/6L90. Thanks

  Every place on the hi-way is up , lowest is the truck stop, $3.93/ 87, the others haven't broken the $4 barrier yet but getting damned close. Lowest diesel $5.73. I haven't checked local yet but I bet they are over the $4 mark. I've been shopping for a type C motorhome and trying not to buy a Ford, found a couple diesels but the price of fuel is scary

  Honestly? I've still been keeping it at about 3000mi. A hair over maybe.
