I had a Trailblazer, with the I-6 version of the same engine, driveshaft through the oilpan too. Surprisingly peppy, and towed my '72 Panther (around 4000 lbs loaded) in the Ozarks with aplomb. I put about 100,000 miles on it (had about 60k when I bought it) and it never gave me any trouble. I'm kinda sorry I traded it.
I've driven Canyorados plenty of times, and I've enjoyed the drive... also, no problems with the ones I experienced.
Honestly, while I do like 4wd, I'm currently jonesing for a z71 4x2 model, 2wd but with a locking rear... and I'd settle for the 4 cylinder version. I don't plan on having a large trailer to haul at any point, maybe something like a foamboard DIY or a Casita. I'd be perfectly comfortable with these little trucks. The I5 has as much power and torque as I care for in the small trucks.
