Kirby the RAM

RAM 3500HD
6.7L Cummins TurboDiesel
Completely Reconditioned

Our Backstory

This truck has been fully reconditioned over the last 2 years.  We intended Kirby, as we named it, to be a major workhorse with us for a long time.  First by pulling our 38-foot 5th-wheel camper all over the country, then pulling a 21,000-lb tiny house.  Plans change, and ours turned out to be for the better, but it meant that we didn’t need Kirby for this purpose anymore after making one trip from Tucson to Portland, Oregon and back again through Wisconsin.

In the meantime, Kirby got a brand-new transmission, turbo-charger, batteries, brakes, suspension, tires, oil changes, a new bed, 5th-wheel hitch, and a host of other things – Click Here to See.  We wanted to make it as new as possible, without spending the $100,000+ that would be necessary to get the reliability, power, and durability that we needed in a new truck.

The only major component not replaced is the Cummins 6.7L Diesel engine.  Not towing, it gets 21MPG actual and 12MPG towing our 13,000-lb 5th wheel RV.  At 157,000 miles, that particular engine is a babe and, if you research it, you’ll see that these powerful engines can easily last well over 500,000 miles.

If you’re looking for a newer, powerful, large truck, you found it.  If you’re looking for an inexpensive used (and maybe abused) vehicle, this is NOT it.

Cummins/AISIN Exhaust Braking

There are two modes for the exhaust brake:

  1. Normal Mode – Full braking, slows down vehicle speed.
  2. Auto Mode – Applies exhaust brake as necessary to maintain speed.

Auto Exhaust Brake works best with the AISIN transmission in Tow/Haul mode and the cruise control set to maintain a specific speed when going up and down mountains.  It worked perfectly for our climbs and descents across the Rocky Mountains in Colorado.

Primary Use

This truck was used by its current owners to tow a 38-foot 5th wheel camper.  We made one trip from Tucson to Oregon to Wisconsin and back to Tucson.  We will not be towing this rig anymore, so there’s no need for such a large and powerful truck.

Performance across the Rocky Mountains was exceptional.  With about 15,000 pounds behind us, we put on cruise control and exhaust brake and made our way across the U.S. with no hesitation or any issues whatsoever.

About The Price

We realize that what we’re asking is above what you’ll find on Kelly’s Blue Book and other listings for the same model year.  What we’re asking doesn’t begin to cover the cost of all the new equipment that’s installed, because we originally had no intention of selling this for years and years, and we wanted it to last and have the same integrity as an almost-new vehicle.  We were quoted a price of $113,500 for a new truck that was similar in towing power and ruggedness.

We are also looking for a small camper to pull with our smaller truck, and we’re willing to barter with someone for a ~4,000 lb standard-hitch camper.

Thank you for your interest.  Kirby has already gone to a new home with people who knew exactly what they were getting.
