I honestly like the original seats in mine. I would however pop in a set from an SR5 if I could run across some. They have additional side bolstering on them. Admittedly, mine are in good shape though, whereas yours are crushed. I'm thinking the 2nd gen seats won't slide forward (passenger side) like the 1st gen in case access through that area will be important to you. I imagine on a long trip like that, access will be important. I'm willing to bet that something that is a minor irritation at first can become a major PITA over time. Think about getting your current seats refurbished at a local shop. That could be cheaper (maybe not), provide a local businessman with some work, and keep your OEM equipment in place.
On the subject of access, I assume you are going to lose the 3 inch body lift. It likely was put on by someone in order to clear the 33's. With 31's you won't need it and can get a lower COG. You can also probably sell it. I'm not an enemy of body lifts by any means (some people hate them), in fact, I have a 1 inch on my truck and it really helps out in some cases to make a bit more room on certain repairs/maintenance. My thinking is more just for ease of you guys getting in and out of the truck. I started building mine into a rock crawler before I discovered the whole Expo concept. That is why it's so big and that is one of the major inconveniences on trips. Getting in and out, loading and unloading is all more difficult. I still like to rock crawl too so it's just going to have to do double duty for a while. I'll probably look for something more stock eventually to build into an Expo rig.
