Good Day to all!!!
Not sure where this thread is going but thought I would add Mine as well:
We actually bought our first GD 303 RLS Fifht Wheel on May 8, 2015, had it until September 11, 2019 when we traded for our exisiting GD 337 RLS Fifth Wheel. Normal Maintenance a couple larger issues, not due to any fault of GD or us and still enjoying.
So, right near the 9 year mark for us with GD as well.
To all as the OP stated:
Safe Travels, Happy Travels and that makes Happy Campers ! ! !
