Next spring I'm going to get a diesel and I've been looking at allot of trucks online. Allot of them take pictures of the dash while truck is idling. I've noticed the oil pressure is around 25-33%. My gas motor is at 50% while in idle so is 25-33% normal for diesel at idle?
My budget only allows used so I've looked at allot of used. Right now I'm looking online, next year I'll try to do some test driving to get a better feel.

I would look at the service/owners manual of whatever truck your looking at for those specs.
With that camper of yours I think you'll be well off with a diesel. I've never owned one but I have a few friends that pull 5th wheels and large campers like yours. They all say without exception they are night and day better than a gas truck.

I think it started out as one of the tricks Cummins used to get more horse power to the flywheel, they used less of the horse power produced pumping oil if they lowered the pressure. The big N14s ran only had 30 psi max but still a lot of volume. If you had more than 10 psi at idle you were good to go.

I'm on diesel number 6, you will never go back to gas once you pull with a diesel. Just take your time, do your research and be patient, you may have to travel to find the one you want, but you'll find one, and I doubt you'll have any regrets once that happens.

Just take your time, do your research and be patient, you may have to travel to find the one you want, but you'll find one, and I doubt you'll have any regrets once that happens. Here in the Omaha area they want top dollar for diesel. My plan is to hear to Texas. I've done allot of research and already learned allot. I like Dodge and Chevy yet I think I'll stick with Chevy. I know the 2001-2004 DuraMax is the years I need to stay away from because of bad injectors. Hoping to find a 2005-07 with around 100k is my goal. What I don't understand is why Dodge can't get transmissions right. If they had a solid transmission I'd consider a Dodge also. Any one of you know much about the Dodge transmission that could help keep it from going out? Or what years to look for that had or has a good transmission.

Any automatic from 95 up in dodge scares me. The new model has a decent transmission. I like the 12 valve Cummins with a 5-speed myself.

About $6-8k in upgrades will fix a Chrysler tranny for good and you'll have a truck that lasts until the body rots away. The only thing to consider about a 100k mile truck is that injectors are gonna need replaced shortly regardless of manufacturer and that is also very expensive in a newer diesel.

I had a 2004.5 Chevy 2500HD with the Duramax LB7 motor. When I traded it almost 2 years ago it had 187,000 hard miles. Pulling a dump trailer most its life and plowing snow every winter. It didn't give me a bit of trouble till about 180,000. I would own another just with lower miles. I sure miss that motor for pulling trailers now. My current truck has a Hemi which is awesome unloaded but im really not impressed with it pulling things.

I've seen some nice trucks around 150k would that be better? I did think about the 100k and injectors however I was told the 08 and newer Chevy DuraMax is a pretty solid motor so thought I'd be okay.

If you find some that have had injectors recently it would be best. It's also good to know who did the injectors and if they were remans who did the work.

Last night I found some site that talked about the DuraMax motor and its development over the years. Said the LB7 was the first production and was ran from 2001-04 said that model had terrible injector issues. Then the next model was the turbo model and was a better motor ran till mid 07. Last was the LBZ motor (I think) and has been in production since. The last two models have been pretty solid from what I read however right now that's the only experience I have with diesel which is why I'm asking a ton of questions and very nervous about diesel.
How hard is it too rebuild an injector and if I buy a rebuild kit will I get enough parts to rebuild all eight?
I found an injector on eBay as a replacement part for around $180-$190 am injector. I still have allot to learn so I have allot of questions please be patient with me. I won't be buying tool next spring so I have allot of research to do also.

As far as injectors go I would only use oem or full force diesel. The eBay specials will have you back under the hood before you know it. Made some terrible mistakes rebuilding 6.0's before and had a buddy go through the eBay injector issue with a duramax. Diesels are great but when buying used it's best to do a lot of research and investigating. A bad day at the dealer can run you 8-10k very quickly.

100,000 miles for a set of injectors? A set of injectors, at least oem should get you at least 250,000 miles. Unless you are pounding the truck.

In my experience no such luck with ultra low sulfer fuel.

Not keeping water out of fuel will eat injectors fast
