Well not new but new to me. Am looking at a Dodge fullsize ext cab late 90's is there anything I shold look out for or try to get i plan on installing a mild lift and some 33 any help from you guys would be hepful :)

If you get a 2000 or 01 with the Off Road Package you can run 33's with no lift and they come with 4.10 gears.:D

If its an auto, make sure that it is working properly. If you are looking at the 360, listen carefully for pinging and check the PCM for a sticker indicating a flash (program change). Typically if it had that, the motor was pinging andtehy retarded the timing and dropped power.

You can actually run 305/70R16's(33x12.50R16's) with no lift. I run a 16x8 wheel with either 4.25 or 4.5" backspacing (i'm horrible at remembering these things) and I get no rub at all, even when flexed out.
