(snip)... To the above response, good lord you are confused, you are spewing wrong advice for how to properly tow a trailer. My guess is you do have not much towing experience and surely haven’t towed with a diesel.
And I'll ASSume you haven't towed enough with your LC. I don't need to tow with a diesel to know that my own vehicle tows my trailer, that is within the manufacturers capacities guidelines, with aplomb. The tool I'm using is rated for this use. I've taken the time to set it up properly. The fact that another vehicle might tow as well (or better) doesn't surprise me. But that doesn't lesson my own vehicles merits or capabilities.
