Dodge Cummins Engine Concern

Does that 1987 have disc rear brakes? I bet not. If it does, you're just plain lucky.
My 2004 GMC seizes up the rear calipers readily if not looked after. Salt damage is LOTS more prevalent in rear calipers than front.

Haha! Good point... Rear drums. Duh! Lol!

My truck has 2499 hours and 81,584 miles. That's an average of 32.6 mph! Not bad.

The "improvement" of rear disc brakes isn't so much in the "salt belt".

My 1991 Silverado had to have several of the brake lines, the gas line and the gas tank replaced due to rust. I eventually traded it in when the rocker panels under the extended cab area rusted through. Wouldn't pass inspection, wasn't worth fixing. Got a 2004 Silverado, Z71, 4x4. Yeah, I know, but the price was right. Replaced one brake line due to rust. About a year later, another one rusted through when my BIL was driving it. I had to replace that brake line and my BIL's underwear. No one hurt when the brake pedal went to the floor and he had to use the emergency brake to stop. I finally had all the brake lines replaced with stainless steel ones.

My '04 Sierra has only 60,000 miles. I have replaced all the brake lines, all the fuel lines (at the same time when the first brake line failed) and the rear bumper due to rust. My rocker panels & cab corners are solid due to front mudflaps from day 1. I'm committed to keeping this truck as I'm not ready to be without a truck, but it is no longer my daily driver for spring, summer & fall. I recently bought a Mini Cooper S hatchback which is infinitely more fun to drive.

Mine has 125,000 miles on it.

Ditto.

I own a Dodge like the OP is looking at....overall great truck.

On the battery subject, I am convinced that heat kills batteries faster than cold.
For me, the most we get is 3 years. Only exception was a Toyota FJ40 that lasted 7 years.

Two batteries in parallel is a crap shoot.

Two batteries in parallel is a crap shoot.

But preferable to two in series.

I own a 2005 2500 Cummins. I only have 36 k on mine and can tell you that mine really didn't break in until 30 k. I went from a solid 19 mpg to 22 mpg right after I turned 30 k. I think a full fluid swap is a good idea along with belt and hoses. I did have the rotors on my truck rot at the edges and tear up the pads and I definitely attribute that to it not being driven. I would also recommend removing the tires especially if you have the aluminum rims and coat the back of the rims with anti seize. I had a **** of a time getting mine of the rotors. I would also change the fuel filter frequently and run Diesel Kleen or some other treatment the first couple of tank fulls Every vehicle I ever owned I usually drove a lot, but I have a company vehicle that I drive to work and its kept the mileage low on my truck. I bought a Dodge because a former employer ran them and didn't maintain them and still got 300k out of them. good luck with it !!!

I probably need to join some truck forum but will ask here as this is less truck and more Cummins engine related and diesel engine to some degree is diesel engine.

I have been looking at, for some time an upgrade to my tow vehicle for moving my equipment.

I most likely will have the opportunity to purchase a 2006 Dodge Ram 3/4 ton truck shortly. Without going into TMI of the personal details of the owner it is a 2006 with a little over 17K miles. Most of that was prior to 3 years ago and in the last three years has had even less with it being driven on Sundays mostly. (no jokes about the grandma car only being driven to church on Sundays)

While I really was looking for a 1 ton for more flexibility I think the 3/4 will do what I need.

My question/concern is:
At 17.1K the engine is barley broken in and after that little use in 8 years and especially in the last 3 years how much/many problems might I be looking at with an engine that has basically been rotting on the vine?
If I get it, it will have a full fluid swap and fuel filter change immediately unless I find evidence that it has been done very recently.

Well it is "a sad day in Mudville" for those that are old enough to understand the phrase.

The owner decided to sell it to a family friend of her father's (it was his truck, rip) and not to her friend, my wife. As a result I will not get the truck. Not happy, disappointed, all that, but, oh well.
Since the owner had been thinking about whether or not she would sell it for months I had put off looking elsewhere as I thought this was a deal worth waiting for.
Now I can look elsewhere without thinking that I missed a deal. I know I missed it, there is no thinking that I might.

But preferable to two in series.

No self discharge problem with series hookup. 2 big 6V would be superior.

Really? My 1987 Chevy has the original calipers.

KY does not use very much salt on its roads.

That's too bad but if you are patient there are other good deals out there.

That must be why every tractor manufacturer quit using 6 volt batteries in series in the 1980's and the owners of earlier tractors using batteries in series have been reconfiguring cables and converting to parallel setups ever since. Not much to debate, so I won' t comment further.

 

[dodge man]

That's a bummer. On the good side you learned a little bit about Cummins trucks.

So what is the reason? Space considerations preventing a large single battery that would essentially be 2 series 6s. The 6V battery is being supported in less and less variety.
,,,.Youre right ... Theres no debate that a larger number of cells [12 vs 6 cells] presents a higher number of potential failure points. And one weak cell in a // system takes down both batts.

 

[MossRoad]

Wether you have two 6v batteries or one 12 v battery, you have the same number of cells.

 

[SPYDERLK]

Wether you have two 6v batteries or one 12 v battery, you have the same number of cells.

Yes. The issue is connecting 2 12s in // to get the grunt of 2 comparable sized 6s in series.

 

[MossRoad]

Ahh. Thank you.

One bad cell in a series system results in an immediate no start. Simply not the case with a parallel system.

Read this thread:
Viewing a thread - Two 12 v batteries vs two sixes volt series&highlightmode=1#M3732771

And I admit to a mistake; IH abandoned 6V batteries in series in the late 1970's.
