BigToe nailed it for me. Wife and I tow with a 2002 7.3 Powerstroke CrewCab. You can hear us coming a hundred yards away. We even disrupt the sounds of young guys with loud music who pull up behind us shaking the pavement!
With about 180K on him, our loyal older truck has never failed to start or get us there pulling our travel trailer.
I keep him in tip top mechanical shape. Only big mechanical improvement has been a Brian's Truck Shop heavy duty transmission built by Brian at his shop in Arkansas to ensure our truck's longevity. Plus I put a Ford Severe Duty air intake put on system him to further increase the engine's longevity. Admittedly, Bilstein shocks and Michelin tires helps his ride.
Now if we pulled together our pennies, we could afford to buy a new Ford SuperDuty that has twice the power and torque, much nicer cabin amenities and is quiet enough to slip upon a thief.
We know there are parts of our truck, which we have named "Bubba", which are wearing out that we do not know about. But, gracious, there are parts of me and my bride of nearly fifty years which are wearing out that we do not know about also.
So we have resolved just to keep ole Bubba, drive him and enjoy him and our little trailer on shorter trips as we age. We try to be considerate campers and not crank Bubba up until after 8:00 a.m. Perhaps we will put on a second pot of coffee in the mornings and wait until it warms up a little. Besides, Bubba runs better when it is a little warmer during the day.
Our Bubba is a good, loyal, friend!
