To be clear I would not have an issue running the "STEEL" ANDERSEN but who wants an adapter in their bed to deal with???
This is what I find simply put a JOKE on the ANDERSEN's website with their Circus type "Crush Test" is the fact the RV simply does not apply all that much down force but they do apply huge fore and aft pressures. Why don't they show those tests??? Simply put they would look like failures compared to the "Crush Test".
"As to strength, the Andersen is rated at 20,000 lbs while the Superglide is rated at 18,000. Andersen has a test video on their website showing the steel Andersen finally breaking at 60,000 lbs of force in a hydraulic press."
