We have the Pinnacle in our sig and are very happy with it. It has gone from the Midwest to Florida a year ago, and this summer we towed it to Alaska for the summer. I estimate we have put about 20,000 miles on it in the two years we have had it. Just after we took possession of it, we had to get warranty work done on a slide seal. Other than that, it has been a great RV.
My only real complaint is that in order to completely dump the black tank, the Pinnacle must be sitting perfectly level or slightly uphill, but this is something we can live with.
This coming spring I will be upgrading to "E" rated tires from the "Ds" that came with it originally. I had a tire slip a belt in Alaska and replaced it with an E which seems to be wearing much better than the originals.
