I have a dodge 3500 crew cab with a Lance 1181. Has anyone had any problem with the frame breaking? Both of my rails broken about mid way of the rear seat.
Broke clean in half or bent? Unless there's corrosion damage, the relatively low ksi steel is unlikely to just snap.
What's the total weight? And off road or big speed bumps at speed?
Being rear heavy, a Lance 1181 should place the weight close to the rear axle. Meaning there's relatively low bending moment around the rear seat area (middle of wheelbase).
