I dont post a ton but to sum it up I traded my 5th wheel for a 2007 jayco seneca 35gs with an lbz with 41,000 miles. Well yesterday josh h built a very nice, and very long exhaust. 4 inch, pipe through the cat,flow through muffler. Egr blocker plate and tuned. Gears are 5:13, empty she is 19,200#. Gets up on the highway and moves well for a big girl. I just wanted to thank my buddy josh as usual for great work. And I will be pulling the dumpster somewhere next season,and prob to the finals.
