Does the foam help the rigidity of the riser or is that just to provide insulation to the bottom of the camper?
Didn't change the rigidity at all, but was used mainly for a little more insulation under my basement. I built the spacer to be able to use it off-truck. S&S said that they wouldn't trust the floor with a full water tank without some additional support under it since it was never designed to be used that way. The other + was the clearance gain, it worked without it on the truck...but my roof lights were REALLY close to the TC. I bought the truck and camper as a unit and sold the truck, so the camper was almost free. there was dents from the previous trucks lights under the C/O, so it needed some kind of spacing to start with.
