Nyogel 760G! Honestly it has been around us forever and it is one of those things nobody has messed with so I've never really been around much else for 20 years. So it's all I know....
White lithium lubes hood pricks and any trucker with Vaseline, well, I don't ask...... 😨😱😏
Diesel heaters aren't that complicated, but they've blessed me with several mortgage payments over the years. Each manufacturer will have a troubleshooting list and repair procedure available, and most of them look a lot alike. Follow the steps, and success is all but guaranteed.
Before we got the hdt, I pulled a 40' cargo trailer w/ living quarters with a truck like yours. Maneuverability is about the same with the Volvo as with the p/u. It would be interesting to hook up with my day cab Mack and try it, as it's about half the length of the Volvo.
