Well that's because it's a Dodge... Dodges/Chrysler's are on a weight reduction plan when they leave the factory.

So is SpeedSpeak2me Chevy

Our shop truck is just as bad, 2013 F250 rusting all around the rear bed wheel arches because of shit seam sealing. So if anyone finds a solid long bed, doesn't matter the color, I'd be a buyer.

That's another worry. GMT-800's and 900's (Speed's), are prone to that same weight loss program. But that's more body issues than anything.

We just live in a shit area for MOST vehicles to survive long term.

Yup, rockers on both sides are gone, and those rear wheel arches turned to dust five years ago. Oh, the bed rails from the wheel tubs going rearwards are gone, and the only thing that resembles the "lip" is the Line-X liner.

Underside of mine is getting pretty "crusty" as SRT41320 put it. The lower 5 or 6 bolts for the rear dff cover are just rusted nubs. Surprisingly the leaf spring shackle mounts (attached to the bottom of the bed) are incredibly solid, aside from some surface rust. I've heard that the mounting point fails, and the top of the shackle punches through the bed.

Summer of 2022 I had it at a shop down by my dad's old place. Guy is a huge GMT800 and GMT900 fan. He said that in recent years mine was the nicest he's driven, all from a mechanical perspective. Was shocked how good the interior was.

I noticed the same on the 400. I had, maybe 3 years ago, replaced the diff fluid on it and when I looked Sunday, I couldn't get over how rusted the bottom cover of the diff was.

Fuck road salt.

I don't want to hijack the thread, but as CMNTMXR57 has seen, I absolutely love my truck. Yesterday, I had the choice to drive it or the car out to White Pines Forest and also the Nachusa Grasslands... You can guess which one I took. Oh wait, you don't have to. I posted it

Edit - I just wish I could afford to get the body issues taken care of. Just made "better", not even back to 100%.

Have we met?

I think we all love our trucks. I love that '99 (and GMT400's in general) and hate to let it go, but it's now ~24 years old (from the in-service date).

Incidentally, I am at 196,247 miles and 5167.9 engine hours.

Flat bed time

Finally got around to installing the new muffler. The OEM one was ugly when I got it out...

And of course... Just the tip... I actually have always had this on, but with cutting up the OEM tail pipe and changing some of the angles, I had to readjust the tip.

Replying to myself.

So now that I've had this on a little over a year now (keep in mind, I don't drive it a heck of a lot in the warm months as I'm driving the cool cars), I think I'm not overly crazy about the sound of this Magnaflow. It is a Magnaflow #12590 which is a dual 3" in, single 3" out mirroring the OEM setup more or less. While they say it's universal fit (meaning you can go either way with it), I think their intended way was the 3" in, dual 3" out. As such, I think it adds a weird resonance in the tone as RPM's increase.

12590 that I have now;

Come spring, I may switch to a Magnaflow #12599. This is a dual 3" in, dual 3" out, with internal "X" pipe. I would then run the second outet pipe of to the drivers side behind that wheel.
