We have a new 2017/2018 Freelander 27 QBC. The posted weight limit tag says 350# Has anyone put two adults at 400# combined and had issues with going over the posted weight limit?
Most things with posted weight limits (or torque limits, or g force limits, etc.) Have some safety margins built in. Manufacturers don't commonly post what those are, but one way to determine that is to test the posted limits by exceeding them to see what happens. Let us know how it works out if you will.
