Thinking of a new truck

[Ozymandias]

Truth is not many folks really need a diesel pickup. Those that do and pull big 5 th wheeler trailers etc would be much better with a semi truck good used etc. I certainly never really needed a diesel but I did need a 1 ton truck to haul my load .But once the diesel monster bites it’s hard to go back. I did really consider buying a 1 ton gasser this time but my love of the Cummins won over again. But I must admit the power train transmission exhaust brake set up the whole power train is pretty awesome. Oh and no exhaust brake on a gasser,once you have one it’s hard to go back

At least you use your all the time with that big heavy camper in the back. That makes a difference.

Only about 4 months a year. But the ho aisin and xbrake makes it a joy to drive

Oh and back up camera and air suspension. Ha sure glad I bought a new truck

6.4 gasser would handle a bumper pull just fine, and you have pretty much the same truck less some hassles of the Regen issues and the extra cost of ownership.

Go rent one each will be like $200 and take them for a drive. Then add on the tech and interior to your comfort level.

But I think you will be happy either way.

I had a 1993 W250, then a 2001.5 2500 and finally a 2015 3500 Laramie with Aisin transmission. Each was a quantum leap forward. I would still be driving the 2015 if I had known how quickly ALS was going to take my DW the summer of 2021.

Trailer Disc Brakes should be an automatic upgrade. Fixes that “problem” (it isn’t one, descent speed is the real cure).

Disc nose to tail

That is one thing I like about driving the work 6.7l trucks is the exhaust brake. Only knock on my EcoD is no EB.

It saves brake pads a lot even when not towing.

Because it is a European engine and they are too stupid - or lazy - to program that little bit of code.
No European diesel below the 7.5T GVW categories has an Exhaust brake.
What a shame. As soon as just one manufacturer would start it, all would have it, but nooo, Noone wants to start..
That fact sets me off every time that topic comes up..

Exactly.

I know I can get a GDE tune to add the somewhat "lame" (from what I read) EB using the vane actuator, but I don't want to mess with my truck's ECM... mostly because I'm under warranty.

When your hauling heavy or pulling heavy a good exhaust brake is just so awesome.Maybe a gasser with a 6 speed manual but they don’t do them anymore

Today I will be traveling SB I-5 Oregon into California with many miles of 6% downhill at over 35k combined. It’s so nice to select your gear and cruise control speed and without touching the brakes safely do it over again snd again. Notice the MC trailer behind the 5er.

Except that the brake controller isn’t applying energy when the EB is in use without service brake.

False sense of security if that’s the case.

Grade descent must include space to go to WOT with emergency application of maximum trailer brake force.

Adverse winds are the bane of trailer towing. Mountain downgrades are where these are most dangerous (natural & man-made). That trailer starts to come around to make a pass (it’s traveling faster downgrade even if fractionally) one has only a few seconds.

Grade descents are not well-managed by RV’ers seen this way. They’re riding the EB same as clueless truck drivers (too high a descent speed and a worse failure in maintaining vehicle separation distances).

This is the norm of today versus prior to thirty years ago when a great deal more caution was evident. Those drivers were more likely to understand that brakes can fail given they may have started driving before the war.

All that’s left is gear choice made . . and steering.

Six Flags Over Texas had a great roller coaster when they first opened, called, The Runaway Mine Train. Every Dad in Texas must’ve used that example with Junior behind the wheel of the combined rig. (“Here’s the REALLY short prayer we’re gonna have you memorize, son”).

Today I wouldn’t any longer drive a tractor-trailer rig without disc brakes on all axles. EB/Trans integration is impressive . . but the basics must be in place.

Has a reputation for disc install on trailers beyond other custom work (them horsey people ain’t afraid to spend).

MOR/ryde is where I’d go to get IS + Disc if both are missing. Increased wheel travel (stability) plus disc clamp force are the only way to proceed. RV hookups at factory for appointment.

EB is only an aid.

The high wind resistance of the RV is your braking energy in this case. EB is a huge aid, period.

With a high wind resistant load (RV) the faster you go down hill the less brakes you need and that's a fact. Might not be a good practice, I don't recommend it, but it is real.

Physics says at some point, the wind resistance will counter the down hill pull. It might be a 100 mph but it is real.

I have hauled loads that you actually had to apply power on a slight down grade.

Now if the road is really steep and crooked and won't allow wind resistant speeds, then yes, you better be in some low gears.

I don't have a point to all this chatter, just talking smack...

Most modern gas pickups today have a tow/haul mode that keeps the torque converter locked. I use that while towing a moderate load of 3300 lbs. I will go down as low as 2nd or 3rd gear(out of 10 available) on Western States passes, and can descend these will little use of service brakes. My F-150 is rated to tow 6600 lbs, and at that weight the tow/haul descend feature will be greatly over powered by that much weight. I manually choose the gear I want to maintain the conservative speed that "I" want go down the grades.
