The rigs need to be built about 4 to 6 inches higher. The folks that go for the IS systems usually go for a 4 to 6 inch I-beam spacer between the new system and frame which brings the entire rig up so that on a lever space the rig has at least 8 to 10 inches clearance.. This would also decrease the pin box dings to rails.

When we had the IS installed in June, a 2x3 tube was welded to the frame with a 2x2 welded to that. After a few issues were resolved and having to install heavier shear springs, the height of the camper went up around 5 inches from its stock height. That is not an issue with Montys of that error. They were only around 12 foot 10 or so to start with.
