I voted for the Nissan only because they have the best engine output. Not sure about how good or bad the truck is, or will be, but Nissan is raising the bar on performance and pwoer out put. That means eventually Chevy and the other guys will do the same. It's all good.
Besides, I noticed that the output figures you posted for the Chevies are for the 5.3L. The base V8 for chevy is the 4.8L, and it puts out 270-275 hp. The 5.3 is an upgrade.
For the sack of comparison, you'd have to compare the base V8 (one step above the V6) of each manufacturer. For the Chevy it's the 4.8L, Dodge is 4.7L, and Ford is 4.6L.
The other option is to compare the Chevy 5.3, the Ford 5.4, and the Dodge 5.7L Hemi (Dodge no longer offers the 5.9L in new trucks).
While I would tend to go for the Silverado before any of the others, I would have reservation only because of the Piston Slap problem that has become evident with the GM engines. Let me clearify that. I have a bigger problem with GM's reaction (or lack of reaction
) to the problem, than the problem itself.
All of that said, I own a 2000 Silverado LS, and I love it!
