I've owned 6 Toyotas; 3 of those were 4Runners. All 3 4Runners were V6's and my current '08 tows my 17' glass bassboat just fine, although if I had to do it over again I'd get the V8 for the extra power. But again, the V6 is nothing to sneeze at.
As far as rugged, I can beat my Toyotas twice as hard as any domestic I've owned and have fewer problems. As far as maintainability, I've probably spent less on maintenance on all 6 of my Toyotas than I did on any two of my domestic vehicles.
I can't speak much on longevity because I usually sell them by the time they reach a little over 200,000 miles and by then, they're only in great condition instead of showroom condition.
