If I use an adapter with my 5th wheel, will it void my warranty?

A few RV/Trailer Frame manufacturers have said (or implied) that they will void the warranty on their 5th Wheel (or frame) if an adapter is used for hooking up. 

Officially, that is illegal. According to the FTC’s Magnuson-Moss Warranty Act they can only void the warranty if the adapter actually CAUSES damage, not simply if it is USED. Additionally they have to PROVE the damage was caused by the adapter.
