I test drove the Chevy Avalanche and then the Nissan Titan. The Titan was roomier by far. It also had exceptional pricing and the buyer receives a lot of quality options at a very good price. MPG was within .5 of rated for both City and Highway. The only option not offered was a hard tonneau cover and outside cab roof lights.
Rear seat storage option PLUS hooks under the rear seats to hold plastic shopping bags. No more bag contents rolling all over the floor!
More beef for the wipers and an option to have a quieter exhaust system.
