We owned a Diesel pusher motorhome manufactured by Thor and it was definitely a lemon. Had the main slide hydraulics replaced twice, and after more than 30 trips to Camping World for adjustment, we decided to cut our losses. Wanted to stay away from any Thor products and always liked the idea of Jayco's 2 year warranty. We looked at the Pinnacles and were impressed with the fit and finish. We are happy so far and have not had the issues that plagued our Diesel pusher.
