All in all it is a great truck, it works and gets the job done.
I have never had issues as far as reliability with my current truck. As with most older vehicles maintaining it is key to keeping it is condition up to standard, I have had suspension issues in the front end but with some basic hand tools and a little time you van can work on most of this truck by yourself if needed. If you are the kind of person who likes decent sound quality and you change out to an aftermarket stereo you will need to upgrade your speakers in order to handle the power pushed out by the new system in order to avoid distortion or blowing the old ones. For a 13 year old vehicle performance wise it still gets up and goes, it is consistent and will get you where you need to go, but again like I said, maintenance. Keep your engine happy, you'll stay happy. Ls trim is close to your base model, you are not really coming with a ton of extra features, you do get dual climate control though so if you run hot and your friends or partner cold, it works out extremely well. Power windows and locks are always a blessing. As far as comfort goes though, if you have lower back pain you will either want to replace the seats or swap out for power seats so you can adjust lumbar and the angle you sit at, the stock seats tend to sit at an angle and put a little more pressure on your lower back which can get irritating after a long day/drive but other than that they're still extremely comfortable seats.
