"IMHO for 12K or so 5er's they are fine. More NO way"
I don't think the above is "bashing".
I give my opinions and anyone can see that the Andersen is no way within 1,000# as strong as the B&W RVK3600 that is directly connected to the frame of my truck. Andersen is 24k rated and B&W is 25K rated compare side by side.
Why "I" would limit the Andersen is because the FACT is the stability with fore and aft movement is supported by the corrugated truck bed.
I know from personal experience with a B&W Companion hitch in my 11 RAM Dually that the base sat on the bed it DID cause bed deflection and even caused the base to distort. B&W stepped up and sent a new base and shims so the base placed fore and aft pressures directly on the beds cross members. YES I had the hitch installed correctly and properly torqued. I was at the top end of the hitch rating.
B&W is VERY conservative in their ratings and Andersen is on the opposite end of their ratings.
Do you believe Craftsman when they say their shop vacs "DEVELOP 6HP" ?
Put a GoPro in the bed of your truck if you are towing at the upper limits of the Andersen and then tell me the bed does not deflect.
I think Andersen has it's place but there is NO WAY I would tow my 23K RV that Andersen says it can tow.
As I always say the above is JMHO.
