Prepurchase questions, things to look for?

Currently have a 2008 ram 6.7 with a g56, and realized after installing double disc clutch that I want an auto or something else. I've decided to keep my eyes open for a nice used 2012-2014 ram... and was looking for stuff to look out for.. .and a few questions

1) Is the 68rfe a decent transmission? I had 47re or whatever in an old cummins truck I had, and it turned into quite the nightmare and quick (with totally stock truck). I dont intend on tuning the motor or anything, just leaving bone stock.

2) Are there any common problem areas you guys can recommend I look at before purchasing? I've got terrible terrible luck buying used. (my current truck has clean carfax, but found out they didnt change fuel filter in like 30k mi, cab is diff white than the bed, bed was kind of beatup under the bed liner etc) I'll know to look out for those things.

3) DEF, was 2013 the first years of the DEF? And does DEF improve mpg vs just the old regen where it dumped diesel into the dpf?

The 68rfe is a solid trans when used the way it was designed to be used, Theres a member on here with over 550,000 miles on a stock 68, hot rodding and racing will kill them quick though. Another thing to look for is service history, make sure it was well maintained, if it has more than 67,500miles then make sure the CCV filter was changed, EGR, EGR cooler, EGR crossover tube, map sensor, DPF, NOX filter were all cleaned. Another thing to stay away from is a previously tuned or deleted truck, most of them will be driven pretty hard, so the trans would be abused. The 13+ trucks will get better mpg in 100% stock form. That's about all I can think of right now, let us know if you have any questions.
