I owned a 05 Canyon 4x4 regular cab 3.5 5 speed for 3 almost 4 years, and put close to 50,000 miles on it. Great trucks, I really beat on mine and it always delivered, quick too being a 5 speed 3.5, However I had a few issues with mine. 1 the front brakes are a "captive" rotor design witch means the unit bearing of the front axles it actually outside the rotor. So if you ever had todo a brake job (Which I highly recommend you do youself, since its very expensive to get it done at a shop) just be aware its not as simple as pulling a rotor off. Second the front axle seals tend to leak overtime, dosn't really effect reliability and they are easy to change out in an afternoon, but it could be used as a nogotiation point (Their will be a little oil around the CV shaft on the differential.). U-joints is always a common failure point ($20 aftermarket ones that are greaseable are a worthy investment). Overall they are easy to work on, cheap to fix and very reliable. I can't speak for anything more than a regular cab on interior space, but their was a lot of room behind the seats, 4WD worked great always and some come factory with a rear locking differential (RPO G80). If you have any questions feel free to PM me.
