Thinking of a used PW 2005 - 2010 anything I should be looking for? I have noticed that some have the factory sliders and some don't personally I'd really like the factory sliders! Am I missing anything else? Are the changes made in 2014 worth financing? - Thanks!
3rd Gens are great if you want to mod and fix lots of stuff. But that is not a good era for Dodge. Body, rust, paint quality, interior quality, issues galore. Think 90's General Motors econoboxes. Just ask about how many people's grab handles fell off or dashes have cracked.
The 4th gens overall have better fit and finish. They changed the suspension in 2014 and added the 6.4L. We do have better on road stock handling and are immune to death wobble with the radius arms. I think the 6.4 is a better fit. We also have bigger axles than the 09-13 trucks. One of the reasons I didn't buy a Power Wagon back in 2013 was that I didn't think the 5.7 was enough for the newer 4th gens. The radius arm trucks kind of already have a long arm, but 4-link can flex out better. And you can always get Thuren alien arms and boom. Now you've got more flex than me.
2013 is the odd ball year, you get the updated interior that the 2014+ trucks have, but you get the 09-12 suspension.
That being said, there are more mod options if you want to go crazy with the 2009-2013 trucks, since they're using leafs out back and 4 link up front. They also feature 4.56 gearing, where my truck a 2015 has 4.10 gearing.
Another thing, the earlier trucks all have true shock mounts, I've got pin tops, which means the biggest I can go without cutting is 2.5 Kings or the like. But my friend with his 2011 has 3.0 Kings up front and 2.5 King bypasses out back.
Circling back around to the 3rd gen trucks, while I don't think it's a good era, and will bring higher maintenance costs I know a lot of people with them who really love them and have owned them for quite some time who are satisfied. It should be also noted, they're a tab bit narrower and have a little more ground clearance because of the design of the lower rocker panels on the two generations.
I've been told the factory offered Mopar sliders were frame mounted.
I suppose, in the end, it depends on what your goals and intentions are and how much comfort you are looking for, along with how much work or maintenance.
