New to forum and to RAM. Considering buying a 2010 2500 Laramie diesel with 135K miles on it. I'm in southern CA so rust is not an issue. It's reasonably priced. I now my question hinges on who owned the truck and what they did with it. Assuming the truck has been maintained and not abused, what problems can I expect? What should I look out for? If buying a high mileage truck is a mistake I would like to avoid it. I appreciate everyone's experience and expertise. Thanks
I avoided most of those issues by buying a used fleet truck that was previously owned by a Car Rental company (most folks who rent a car usually don't rent a truck that doesn't have a hitch on it, and Enterprise is very decent at maintaining their vehicles.)
Now in your case, not too many places have a 2500 as a fleet truck that doesn't also beat the crap out of them, due to the nature of what they were bought for (construction, semi-heavy deliveries, big agriculture, etc.), so you're pretty much stuck with private sales if you want the truck to last. However, if you can, ask for all of the maintenance records on the truck, get a solid Carfax report, and make sure all the recalls were done on it (you can get a list of those at mopar.com by entering the VIN there).
The rest applies to any brand of truck really (especially HD diesel trucks), but if I were you...
135k miles is well beyond the reach of any service contract that isn't a ripoff, so you will also want to take the truck to a mechanic and pay said mechanic to look it over, nose to tail. Also make sure you set aside and/or save up $3k-$5k in your savings account (before you buy the truck) and leave it alone, just in case you have to fix it (it'll give you just as much peace of mind.)
