I can come down from Blowing Rock, 7 miles of 6 to 7% grade, with sharp curves and hardly touch the brakes.

In a gas truck you gear down and hope you don't blow the motor by over revving it coming down or up a step grade. Have you ever driven a diesel? Exhaust breaks are added to diesel to pull loads you can only dream of pulling with a gasser.
The trailer he is holding back only MAX 7,000# more likely south of 6,000#. My Cummins did fine without an EB with our 1st 5er at 8,000# and 7,500# of truck.
Yep an EB is an add on, but having a turbo mounted on on an engine with 17 to 1 compression is a lot of Whoa!
Terryallan, your whole rig likely weighs about as much as just my 11,000# 5er.

But you should recoup a lot of that on the back end when you sell or trade.
I find that hard to believe - if you buy a diesel today, at say anywhere from $7k - $9K over a gas version, and you get down around 250K-300K miles or so, you have an older worn out body and seats, and heater, and A/C, and wires, and alternators, and undercarriage, and etc etc... So, what makes anyone imagine a truck of that age will bring $7k or $9k more than a gasser,
You have a diesel engine that runs like new still in an old worn out truck even if you take care of it. The reason one buys a diesel is pulling power ... it never will have anything to do with resale value or operating expenses. Or, recovering that expense when you sell it. Can't...makes no sense.

Try that with 15k lbs on your tail Terry and get back to us with your results :E Think brake fade here. "hardly" means your service brakes are warm to put it mildly. Most likely hot and in a failing state, err not exactly what the manufacture engineered it for.
Your call, but the gasser back pressure is very limited with a big RV.
BTDT :E

I knew when I bought my diesel truck that the cost for the truck was going to be $9,000 more and that I would be paying twice as much for maintenance and repairs, but I did not expect to be paying more for diesel than for premium gas.
I have been checking prices and locations for a trip planned through California, Oregon, Idaho, Montana, and Nevada this year. I was surprised in checking Pilot truck stop prices how much more they are charging for diesel over premium gas.
In California the difference is on average 8 cents.
In Oregon the difference on average is 22 cents.
In Idaho the difference on average is 55 cents.
In Montana the difference on average is 60 cents.
In Nevada the difference on average is 25 cents.
That difference in cost is twice as great when comparing diesel to the regular gas that a truck would be using. In Montana diesel is 90 cents more per gallon than diesel or 29% more expensive. That pretty much wipes out any gain in fuel economy from having a diesel engine.

Just a cursory observation.

Oh, and I want one that will come down 6% grades at a reasonable speed with the trailer without using the service brakes.
