I am looking at buying this truck used. It has 25k on it. Whats your opinions of the truck? Anything to look at? Any problems or upgrades needed?

Thanks

Emissions crap is a problem, no legal fix. My 08 quad cab 4x4 2500 had a payload of 1800 pounds, which is pathetic, and I imagine a mega cab weighs a few hundred pounds more.

their newest trucks have a higher payload capacity than that...

2500 short bed has 2534lb capacity
2500 long bed has 2382lb capacity (yes the short bed has higher payload capacity)

this does not hold true for the 3500 though, but we are only talking 2500 here

2194lb capacity for the megacab 2500

(all 2013 specs)

Of course the short bed has a higher payload - they've got the same gross weight but the short bed weighs less.

It's nice that they bumped the gross weight up to 10k.

No real problems. All in all they're great trucks. Buy it.

I have 105,000 miles on my 2010 2500 megacab and only problems it has had were warranty repairs.

soon as warranty runs out, delete the DPF, EGR, and get a delete programmer.

I bought the truck today. What exactly does deleting the DPF,EGr, and programmer do?

Do I need to run a lubricant like AMSOIL or Diesel Clean? What does it do for the truck?

Well, as you'll find out, mileage sucks stock. Numbers vary widely, but around 15 is probably a good average. There is also some complications that some have with the emissions. Deleting, while illegal and will get you in trouble if you live where inspections and emissions checks take place, gets you better mileage, more power, and eliminates the problem areas of the truck.

Some guys live by Amsoil and additives, I personally avoid them. Amsoil is a name with no real added benefits that I've seen, and additives haven't shown their worth to me either.

Amsoil is a MLM cult, they sell decent oils but G. D. they're expensive.

Additives, however, cannot hurt since all of the stuff that made the older fuel and oils good, has been stripped out.
