I bought a 2018 Colorado ZR2 on May 8th. It was an impromptu purchase brought on by the death of my 2005 Trailblazer LS after 254K miles (2nd owner after 31K miles). The first day of our 3-week travel trailer trip from the SF Bay Area to San Diego, Anza-Borrego and Sequoias National Forest, the TB overheated in Paso Robles, CA. Had it towed to Grover City since we were staying at a RV site in Oceano, CA. The engine failed pressure test, indicating several different possibilities that resulted in replacing the engine. The shop wanted $7400 to install a used motor with 133K miles on it. I immediately got on the phone looking for a ZR2. Of course, I just spent the previous month modifying the TB with 2" body lift, 2.2" suspension lift, custom steel bumper, 13,000 lb winch, all new front suspension, new Bilstein 5100 shocks all around and a Smittybilt Jeep JK swing-away tire carrier modified to fit the original TB rear bumper. The dealer in SLO where I bought the ZR2 is storing the TB for me until I can haul it back home after our 3-week trip. There were three used ZR2s available in the between Paso Robles and Santa Maria, CA.. I bought mine from San Luis Obispo. It had 61K miles. Cost was $29K including a 48 month/48K mile factory warranty. It is a Chevrolet Certified Used Vehicle. Anyway, that's why I am the proud new owner of a 2018 Colorado ZR2. When I return to the Bay Area, I'll be buying a DECKED truck bed drawer system and a Go Fast Camper. Let the Overlanding begin!!
