I have had no problems with this truck of any kind. Owned it for two years. The interior is really comfortable for long drives. Fits both car seats in the back and tows anything I put on the back of it. Of course mileage is bad but most trucks do not get good mileage. If you want good mileage go buy a Metro and park the truck. My truck has the 5.2L.
Reliability is outstanding. Roomy interior is great. Easy to work on.
Everyone would like great gas mileage but then all the power for towing would go away. The improvement I would make is the ability to view traffic on my left over my shoulder. The A-arm pillars are rather large and bulky. Traffic can be hard to see around cab structure at times.
