I got the eTorque in my Limited because auto stop/start is quite helpful where I live, and I spend on average 5 minutes idling out of a 45 minute commute. Now I just let the auto stop/start shut off the engine at lights, and if I remember, I turn off climate control beforehand so it stayed stopped for the whole light... profit!
It's also quite well-engineered. It's as unobtrusive as I've experienced in anything less than a full-on hybrid. The battery tech and motor/generator are all existing tech, just applied differently here. Sure, it's more stuff to break, but I thought I'd give it a shot.
As for the RAM Boxes, I wanted the extra payload, so I skipped them. They weigh somewhere around 160lbs, so if you're looking at a loaded-up Limited, your payload can get quite low - I think Car & Driver's test vehicle had a 990lb payload. My truck, with almost all the trimmings except RAM Boxes, says 1,320lbs on the red/yellow payload sticker.
My truck also has the 22" wheels. What's funny is that I test drove a truck with the standard 20" wheels on it, and didn't like the ride - it felt harsher. Plus, I like the look of the 22s.
At the end of the day, YOU have to be happy with your truck. If you live in or near a city and idle a lot, go ahead and get the eTorque. If you want built-in bed-side storage and are willing to give up some payload capacity, get the RAM Boxes. If you like the 22s, get the 22s.
